x86/rtc: Rename mach_set_rtc_mmss() to mach_set_cmos_time()

Once upon a time, before this commit in 2013:

   3195ef59cb42 ("x86: Do full rtc synchronization with ntp")

... the mach_set_rtc_mmss() function set only the minutes and seconds
registers of the CMOS RTC - hence the '_mmss' postfix.

This is no longer true, so rename the function to mach_set_cmos_time().
