efi_set_rtc_mmss() is never used to set RTC due to bugs found
on many EFI platforms. It is set directly by mach_set_rtc_mmss().
Hence, remove unused efi_set_rtc_mmss() function.

v6 - suggestions/fixes:
- remove efi_set_rtc_mmss() instead of commenting out it
(suggested by Stefano Stabellini, Juergen Gross,
H. Peter Anvin and Matt Fleming).
