This series does some cleanup and precursor changes to the hyper-v clock
source and introduces support for TSC page based clock in root partition.
Hyper-V root partition requires kernel to map the page, specified by the
hypervisor (instead of provide the PFN to the hypervisor like it's done in
guest partition).
v3:
1. Rebased on top of the fix to support arbitrary TSC page size by Anirudh
2. Fixed TSC physical page when remapping in root partition.
v2:
1. Addressed all the comments to the commit messages.
2. TSC page in root partition is now remapped based on size of the tsc_pg
variable.
The following series implements...
