Skylake: remove the out-dated VR config and un-needed 24mhz calibration
On Skylake, mailbox interface is used to configure VRs, dropping direct msr
writing. With current fsp, svid/vr programming seems to be functional - no
errors are given in the svid transactions in boot, and hw engineer verified
the VRs on Kunimitsu. Additional tunnings might be needed later with power
testing.
24mhz calibration is no longer needed on Skylake due to bclk archtecture
change.
BRANCH=none
BUG=chrome-os-partner:45387
TEST=Built and boot on kunimitsu/glados, reboot, S3/resume verified.
