This sets both fwrt->uats_valid and returns 0, but in the
static inline it returns 0 without setting uats_valid,
which is confusing and the iwlmvm code misbehaves in this
case.
Since it already sets uats_valid, just remove the extra
return value.

We are currently reading it only from ACPI, but we need to read it from
UEFI too (if exists, and if the UEFI variables are locked)
Add the reading from the UEFI and use IWL_BIOS_TABLE_LOADER to generate
the code that determines the source from which the table should be read
(ACPI/UEFI).
