x86: Make EFI RTC function depend on 32bit again
The EFI RTC functions are only available on 32 bit. commit 7bd867df (x86: Move get/set_wallclock to x86_platform_ops) removed the 32bit dependency which leads to boot crashes on 64bit EFI systems.
Add the dependency back. Solves: http://bugzilla.kernel.org/show_bug.cgi?id=14466
