ACPICA: Delete stale FADT functions outside tbfadt.c.
Moved all FADT-related functions to a new file, tbfadt.c. Eliminated the acpi_hw_initialize function - the FADT registers are now validated when the table is loaded. Signed-off-by: Alexey Starikovskiy <alexey.y.starikovskiy@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
