Both the secondary and subordinate bus numbers are configured in this
function but it's not easy to search for in the tree as the PCI writes
are hidden inside a bigger write to 'PCI_PRIMARY_BUS'. Use separate
variables and PCI config writes to improve the readability.

In order to cache the spd data which reads from the memory module, we
add SPD_CACHE_ENABLE option to enable the cache for the spd data. If
this option is enabled, the RW_SPD_CACHE region needs to be added to
the flash layout for caching the data.
Since the user may remove the memory module after the bios caching the
data, we need to add the invalidate flag to invalidate the mrc cache.
Otherwise, the bios will use the mrc cache and can make the device
malfunction.

This patch removes Rcomp settings. In MRC design, it checks if the
Rcomp settings from the board is 0 or null, if so, it uses the
recommended Rcomp values. Otherwise, it uses the Rcomp settings passed
from the UPD. From the change history of MRC, we're chasing a moving
target. This RCOMP setting in coreboot is an old setting while the
Rcomp settins in MRC are optimized settings. Moving forward, if there
is a new stepping, it might be changed again which increases the
maintenance effort in coreboot. IMHO, we should let MRC to set the
optimized RCOMP values for the design.

Currently the LPIT Get Constraints _DSM subfunction returns a package
containing the path to a nonexistent device (\NULL). This is used to
work around an issue with Windows, where returning an empty package will
cause a BSOD. However, using this non-existent device can also cause
confusion, as on Linux, it shows an error in dmesg, e.g.
ACPI Error: AE_NOT_FOUND, While resolving a named reference package
element - \NULL (20200925/dspkginit-438)
Therefore, this patch modifies this returned package slightly to include
the path to ACPI_CPU_STRING for CPU 0, which should always be emitted on
Intel platforms that use the PEP driver.

This fixes no practical problem, especially for coreboot where only
one process should access the SPI controller. It makes the code look
more spec compliant.
As per EDS, SPI controller sets the HSFSTS.bit5 (SCIP) when software
sets the Flash Cycle Go (FGO) bit in the Hardware Sequencing Flash
Control register.
Software must initiate the next SPI transaction when this bit is 0.
Add non-blocking mechanism with `5sec` timeout to report back error
if current SPI transaction is failing due to on-going SPI access.
