This patch moves uart functions which are common across multiple soc to
block/uart. This will remove redundant code copy from soc
{skylake/apollolake/cannonlake}.
BUG=b:78109109
BRANCH=none
TEST=Build and boot on KBL/APL/CNL platform.

This patch ensures all Intel common PCI devices can
have subsystem ID programmed along with PCI resource
enabling (.enable_resources) as part of PCI enumeration
process.
TEST=Build and boot KBL/CNL/APL/GLK to ensure PCI
subsystem ID getting programmed.
Example:
Enabling resources...
PCI: 00:00.0 subsystem <- 8086/590c
PCI: 00:00.0 cmd <- 06
PCI: 00:02.0 subsystem <- 8086/591e

It has been observed on a number of platforms (baytrail, kaby lake)
that if serial console is not enabled in coreboot, but is enabled in
kernel (v4.4), then on resume kernel hangs. In order to fix this, add
support for enabling UART debug port controller on resume.
In order to decide whether UART debug port controller should be
enabled in ramstage, following things are checked in given order:
1. If coreboot has serial console enabled, there is no need to
re-initialize the controller.
2. This special action is taken only for UART debug port controller.
3. If boot is not S3 resume, then initialization is skipped.
4. Callback into SoC to check if it wants to initialize the
controller.
If all the above conditions are met, then UART debug port controller
is initialized and taken out of reset.
BUG=b:64030366
TEST=Verified with the entire patchset series that:
1. If coreboot does not have serial console enabled, but Linux kernel
has console enabled, then on resume, coreboot initializes UART debug
port controller.
2. If coreboot and Linux do not have serial console enabled, then
coreboot does not initialize UART debug port controller.
3. If coreboot has serial console enabled, there is no change in
behavior.

1. Create a new function uart_lpss_init which takes the UART LPSS
controller out of reset and initializes and enables clock.
2. Instead of passing in m/n clock divider values as parameters to
uart_common_init, introduce Kconfig variables so that uart_lpss_init
can use the values directly without having to query the SoC.
BUG=b:64030366
TEST=Verified that UART still works on APL and KBL boards.
