The sfi_mrtc_array[] only gets initialized when the sfi mrtc
table is parsed, so the vrtc_paddr should be initalized after it
too.

If we don't assign Moorestown specific wallclock init and ops function
the rtc/persisent clock code will use cmos rtc for access, this will
crash Moorestown in that the ioports are not present.

Also in vrtc driver, should avoid using cmos access to check UIP status.

Moorestown platform doesn't have a m146818 RTC device like traditional
x86 PC, but a firmware emulated virtual RTC device(vrtc), which provides
some basic RTC functions like get/set time. vrtc serves as the only
wall clock device on Moorestown platform.
