Hi all,

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.

Currently, vrtc init func need be called before xtime's init, thus move
xtime's init into a subsys_initcall: timekeeping_late_init() as suggested
by Thomas

Please review these patches.

Thanks,
Feng

Changelog:
v2:
* add IPC cmd for setting time
