Revert "ACPI: sleep: Put the FACS table after using it"

Commit 70dd6c2345cd ("ACPI: sleep: Put the FACS table after using it")
puts the FACS table during initialization.

But the hardware signature bits in the FACS table need to be accessed,
after every hibernation, to compare with the original hardware
signature.

So there is no reason to release the FACS table mapping after
initialization.

This reverts commit 70dd6c2345cdb04fd928e7c4111ad5e98c5d18cd.

An alternative solution is to use acpi_gbl_FACS variable instead, which
is mapped by the ACPICA core and never released.
