Commit dc666f5 (soc/intel/cannonlake: Change in SaGv options) added a
conditional preprocessor directive, but its condition was incorrect
because SOC_INTEL_CANNONLAKE is selected for CNL, CFL and WHL. Thus, an
explicit check for !SOC_INTEL_COFFEELAKE is required.
While we are at it, clean up the comment above a bit.

The option to specify a binary file name was added later for platforms
that do not provide microcode updates in our blobs repository. Alas,
it wasn't visible what platforms these are. And if you specified a file
for a platform that already had one, they were all included together.
Make it visible which platforms don't provide binaries with the new con-
figs MICROCODE_BLOB_NOT_IN_BLOB_REPO, MICROCODE_BLOB_NOT_HOOKED_UP and
MICROCODE_BLOB_UNDISCLOSED. Based on that we can decide if we want to
include binaries by default or explicitly show that no files are inclu-
ded (default to CPU_MICROCODE_CBFS_NONE).
Also split CPU_MICROCODE_CBFS_GENERATE into the more explicit
CPU_MICROCODE_CBFS_DEFAULT_BINS and CPU_MICROCODE_CBFS_EXTERNAL_BINS.
And clean up the visibility of options: Don't show CBFS related options
on platforms that don't support it and don't show external file options
if the platform uses special rules for multiple files (CPU_MICROCODE_
MULTIPLE_FILES).

The GPIO drivers in Windows and Linux for the Cannonlake CPU
have a sparse GPIO map and do not allocate pins contiguously.
Each GPIO group is allocated as 32 pads regardless of whether
the hardware actually has that many in the group.
It appears this originated with a bug in Windows/UEFI and was
carried over to Linux in order to work with existing firmware:
https://lore.kernel.org/patchwork/patch/855244/
In order to support using ACPI GPIOs it is necessary for coreboot
to be compatible with this implementation. The GPIO groups that
are usable by the OS are declared with a pad base which is then
used to compute the number for ACPI GPIOs.
BUG=b:120686247
TEST=tested with write protect GPIO on sarien board. Before this
change the ACPI pin number was 220 which did not correspond to the
pin number in Linux. After this change the ACPI number is 303,
which maps to the correct GPIO in Linux. Now the GPIO value reported
by the kernel changes when the WP pin is toggled in hardware.
