Starting with Meteor Lake SoC, the PCR/DMI interface to program GPMR
is replaced with IOC (I/O Cache), hence, this patch implements IOC
driver to support that migration.

The fast SPI controller (usually handling the boot NOR flash) is a
different controller type than the generic SPI controllers as it
provides access to the boot flash and usually is not used for generic
SPI slave connections.
Though there is common code for the fast SPI controller it currently do
not uses the PCI driver structure. This patch adds the PCI driver
envelope to the fast SPI driver and moves Apollo Lake as the first
platform to this driver.

Since coreboot locks GPIO registers after GPIO configuration, OS is not
able to program GPE_EN register to program wake events. This causes
the issue of event not getting logged into event log (since GPE_EN bit
is not set).
GPE_EN register programming is required for the GPIO pins which are
capable of generating SCI for the system wake. Elog mechanism relies
on GPE_EN and GPE_STS bit to log correct wake signal.
This patch add supports to program GPE_EN register before coreboot locks
the GPIO registers. Note that coreboot will only program GPE_EN bits for
GPIO capable of generating SCI.
This will help resolve issue where we don't see wake event GPIO in event
log.
