intel_mid: Renamed *mrst* to *intel_mid* Following files contains code that is common to all intel mid soc's. So renamed them as below. mrst/mrst.c -> intel-mid/intel-mid.c mrst/vrtc.c -> intel-mid/intel_mid_vrtc.c mrst/early_printk_mrst.c -> intel-mid/intel_mid_vrtc.c pci/mrst.c -> pci/intel_mid_pci.c Also, renamed the corresponding header files and made changes to the driver files that included these header files. To ensure that there are no functional changes, I have compared the objdump of renamed files before and after rename and found that the only difference is file name change.

x86: mrst: Add vrtc driver which serves as a wall clock device 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.

x86: Fix vrtc_get_time/set_mmss to use new timespec interface The patch "x86: Increase precision of x86_platform.get/set_wallclock" changed the x86 platform set_wallclock/get_wallclock interfaces to use nsec granular timespecs instead of a second granular interface. However, that patch missed converting the vrtc code, so this patch converts those functions to use timespecs. Many thanks to the kbuild test robot for finding this!
