x86, realmode: Unbreak the ia64 build of drivers/acpi/sleep.c
Revert usage of acpi_wakeup_address and move definition to x86 architecture code in order to make compilation work in ia64. [jsakkine: tested compilation in ia64/x86-64 and added proper commit message] Reported-by: Paul Gortmaker <paul.gortmaker@windriver.com> Originally-by: H.
