ACPI: Use _TSS for throttling control, when present. Add error checks.
_TSS was erroneously ignored, in favor of the FADT.
When TSS is used, the access width is included in the PTC control/status
register. So it is unnecessary that the access bit width is multiplied by 8.
At the same time the bit_offset should be considered for system I/O Access.
It should be checked the bit_width and bit_offset of PTC regsiter in order to
avoid the failure of system I/O access. It means that bit_width plus
bit_offset can't be greater than 32.
