The iosf access functions already use some common code,
however there is a duplication for setting up the proper
control register for port and opcode. Introduce macros
to remove this verbosity.

The reg_script library has proven to be useful. It's
also shown that many scripts operate on devices. However,
certain code paths run the same script on multiple,
but different, devices. In order to make that easier
introduce reg_script_run_on_dev() which takes a device
as a parameter. That way, chained reg_scripts are not
scrictly needed to run the same script on multiple devices.

This adds the option to put LPSS and SCC devices into ACPI mode
by saving their BAR0 and BAR1 base addresses in a new device
NVS structure that is placed at offset 0x1000 within the global
NVS table.
The Chrome NVS strcture is padded out to 0xf00 bytes so there
is a clean offset to work with as it will need to be used by
depthcharge to know what addresses devices live at.
A few ACPI Mode IRQs are fixed up, DMA1 and DMA2 are swapped and
the EMMC 4.5 IRQ is changed to 44.
New ACPI code is provided to instantiate the LPSS and SCC devices
with the magic HID values from Intel so the kernel drivers can
locate and use them.
The default is still for devices to be in PCI mode so this does
not have any real effect without it being enabled in the mainboard
devicetree.
Note: this needs the updated IASL compiler which is in the CQ now
because it uses the FixedDMA() ACPI operator.

TEST=manual tests on rambi device:
1) build and boot with devices still in PCI mode and ensure that
nothing is changed
2) enable lpss_acpi_mode and see I2C devices detected by the kernel
in ACPI mode. Note that by itself this breaks trackpad probing so
that will need to be implemented before it is enabled.
3) enable scc_acpi_mode and see EMMC and SDCard devices detected by
the kernel in ACPI mode. Note that this breaks depthcharge use of
the EMMC because it is not longer discoverable as a PCI device.

Make all three coreboot stages (bootblock, romstage and ramstage) aware of the
architecture specific to that stage i.e. we will have CONFIG_ARCH variables for
each of the three stages. This allows us to have an SOC with any combination of
architectures and thus every stage can be made to run on a completely different
architecture independent of others. Thus, bootblock can have an x86 arch whereas
romstage and ramstage can have arm32 and arm64 arch respectively. These stage
specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain
and compiler flags for every stage.
These options can be considered as either arch or modes eg: x86 running in
different modes or ARM having different arch types (v4, v7, v8). We have got rid
of the original CONFIG_ARCH option completely as every stage can have any
architecture of its own. Thus, almost all the components of coreboot are
identified as being part of one of the three stages (bootblock, romstage or
ramstage). The components which cannot be classified as such e.g. smm, rmodules
can have their own compiler toolset which is for now set to *_i386. Hence, all
special classes are treated in a similar way and the compiler toolset is defined
using create_class_compiler defined in Makefile.
In order to meet these requirements, changes have been made to CC, LD, OBJCOPY
and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others.
Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the
toolsets are defined using create_class_compiler.
Few additional macros have been introduced to identify the class to be used at
various points, e.g.: CC_$(class) derives the $(class) part from the name of
the stage being compiled.

Rambi has 3 pins that need to be configured for SCI and SMI:
1. GPIO_CORE[0] - runtime SCI pin
2. GPIO_SUS[7] - SMI for firmware lid events
3. GPIO_SUS[0] - wake pin for S3 wakes from EC.
Configure these pins now that the rest of the infrastructure
is in place. The one thing that is yet to work is runtime SCI
for lid events once booted.
