When the SCI_EN bit is set, PM1 and GPE0 events will trigger a SCI
instead of a SMI#. However, SMI_STS bits PM1_STS and GPE0_STS can
still be set. Therefore, when SCI_EN is set, ignore PM1 and GPE0
events in the SMI# handler, as these events have triggered a SCI.
Do not ignore any other SMI# types, since they cannot cause a SCI.
Note that these bits are reserved on APL and GLK. However, SoC-specific
code already accounts for it. Thus, no special handling is needed here.

This patchs adds a new CBFS primitive that allows callers to pass in an
allocator function that will be called once the size of the file to load
is known, to decide on its final location. This can be useful for
loading a CBFS file straight into CBMEM, for example. The new primitive
is combined with cbfs_map() and cbfs_load() into a single underlying
function that can handle all operations, to reduce the amount of code
that needs to be duplicated (especially later when file verification is
added). Also add a new variation that allows restraining or querying the
CBFS type of a file as it is being loaded, and reorganize the
documentation/definition of all these accessors and variations in the
header file a little.

This patch pulls control of the memory pool serving allocations from the
CBFS_CACHE memlayout area into cbfs.c and makes it a core part of the
CBFS API. Previously, platforms would independently instantiate this as
part of boot_device_ro() (mostly through cbfs_spi.c). The new cbfs_cache
pool is exported as a global so these platforms can still use it to
directly back rdev_mmap() on their boot device, but the cbfs_cache can
now also use it to directly make allocations itself. This is used to
allow transparent decompression support in cbfs_map().
