On mc_apl2 the external RTC is connected to I2C bus 3. All other I2C bus
devices (16.0, 16.1 and 16.2) have been disabled as they are not used.
While coreboot can handle the case where a PCI device does not have
function 0 enabled but a later one (here function 3), Linux seems to
check for function 0 first and ignores the rest if function 0
is missing. So enable PCI device 16.0 in order to let Linux use 16.3
again.
Test=Boot into Linux and make sure that PCI device 16.0 and 16.3 are
visible and I2C attached RTC works properly.

The mainboards mc_apl{2,4,5,6} use VBOOT for verification and can be in
a recovery state for different reasons. In this case we still want the
MRC cache to be around to avoid the DRAM retraining on every boot.
This patch enables the Kconfig switch HAS_RECOVERY_MRC_CACHE which makes
the already available MRC recovery region in FMAP useable.
Test=Boot mc_apl2 in recovery mode and make sure the recovery MRC
cache is used.

The only option to make HECI1 function disable on Elkhart Lake SoC
platform is using SBI under SMM mode.
List of changes:
1. Drop `HeciEnabled` from dt and dt chip configuration.
2. Replace all logic that disables HECI1 based on the `HeciEnabled`
chip config with `DISABLE_HECI1_AT_PRE_BOOT` config.
Mainboards that choose to make HECI1 enable during boot don't override
`heci1 disable` config.

The preferred location for the SPD data on mc_ehl based boards is the
HW-Info data structure. Inside this structure there is a field of 128
bytes available for the SPD data. So in order to use it construct a
buffer in memory which is 256 bytes long (as FSP requests minimum 256
bytes for the SPD data) and where the upper 128 bytes are taken from
HW-Info holding the needed timing parameters for LPDDR4.
If there is a case where HW-Info is not accessible or where the
contained SPD data is not valid (by checking the CRC in HW-Info SPD)
fall back to fixed SPD data set in CBFS.

This board has the RTC RX6110SA connected to the I2C2 instead of SMBus
as in mc_ehl1. Set the bus speed for I2C2 to 100 kHz, since this RTC
only supports the standard speed.
TEST:
- Console Log shows no errors for RX6110SA during I2C2 init
- Finalize device for I2C 00:32 shows correct date and time

Since this variant uses different DDR4 devices compared to mc_ehl1 in a
memory down configuration, the SPD data file must be adapted.
In a first configuration we use Micron MT53D512M32D2NP modules.
Following values were adjusted according to this board characteristic
and with help of Serial Presence Detect (SPD) for LPDDR3 and LPDDR4
SDRAM Modules JEDEC Spec and the Specification for this Micron modules
itself:
- SPD Byte 4 - only 4Gb density instead of 8Gb for mc_ehl1
- SPD Byte 5 - different Row and Column Address Bits
- SPD Byte 29/30 - 4Gb LPDDR4 needs 130ns tRFCab
- SPD Byte 31/32 - 4Gb LPDDR4 needs 60ns tRFCpb

If `common_soc_config.chipset_lockdown` is not configured with

provide a flashmap for partitioning. Select the used flashmap on variant

Add a new mainboard called mc_ehl which is based on Intel's
'elkhartlake_crb'. This commit simply copies the mainboard directory and
adjusts the naming to match the new board's name. Follow-up commits will
introduce the needed changes for the new mainboard.

The I2C bus at which the external RTC is attached to is operated at
standard speed (100 kHz) at coreboot runtime. The OS can choose to run it
at fast speed since it uses its own driver and controller setup.
Report additional bus timings for fast mode so that OS can do it right.

Already released Linux versions did not have the needed ACPI-extension
in the RTC driver. If the ACPI-Support is enabled for the RTC, this
older Linux will not be able to use this device as it will be claimed by
the PNP-drivers. As there is no way to avoid that an older Linux kernel
meets a newer coreboot in the field, we need to disable the ACPI
support for the RTC for the mc_apl-based mainboards.

All the boards in the patch have a constraint for the I2C bus to operate
on 100 kHz. Provide dedicated values for rise time, fall time and data
hold time on mainboard level to get a proper timing which takes the bus
load into account. Giving these values the driver computes the needed
timings correctly.
TEST=Measure I2C frequency on all boards while coreboot accesses
external RTC and make sure it is 100 kHz.

UART pad configuration should not be done in common code, because that
may cause short circuits, when the user sets a wrong UART index. Thus,
add the corresponding pads to the early UART gpio table for the board as
a first step. Common UART pad config code then gets dropped in CB:48829.
Also switch to `bootblock_mainboard_early_init` to configure the pads in
early bootblock before console initialization, to make the console work
as early as possible. The board does not do any other gpio configuration
in bootblock, so this should not influence behaviour in a negative way
(e.g. breaking overrides).

There are some objects that are common to all platforms,
and some that should be declared only conditionally.
Having a top-level ASL helps to achieve this.
