x86 ACPI: normalize segment descriptor register on resume
Some Dell laptops enter resume with apparent garbage in the segment
descriptor registers (almost certainly the result of a botched
transition from protected to real mode.) The only way to clean that
up is to enter protected mode ourselves and clean out the descriptor
registers.
This fixes resume on Dell XPS M1210 and Dell D620.
