Subject: x86, realmode: Move ACPI wakeup to unified realmode code

Migrated ACPI wakeup code to the real-mode blob.
Code existing in .x86_trampoline  can be completely
removed. Static descriptor table in wakeup_asm.S is
courtesy of H. Peter Anvin.

Subject: acpi, bgrd: Add missing <linux/io.h> to drivers/acpi/bgrt.c

The ACPI BGRT driver uses ioremap() and memcpy_fromio(), which means
it needs to #include <linux/io.h>.

[ hpa: This was hidden because <asm/acpi.h> used to include <asm/trampoline.h>,
  which then included <asm/io.h> ]
