[PATCH 1/1] x86: Hyper-V: Mark the Hyper-V clocksource as being high resolution

["K. Y. Srinivasan" <kys@microsoft.com>]

From: Vivek yadav <vyadav@microsoft.com>

By design, alternative clock sources listed are based on the resolution of
current clock source. Once you set a  high resolution clock,
only high resolution sources are returned.
Mark Hyper-V clock source as a high resolution clock source.
