On Arcturus, we need TC channel hashing, which is set by the
driver, to match DF hashing, which is set by VBIOS. To match
these, we plan to query the DF information and then properly
set the TC configuration bits to match them.
This patch adds the required fields to register definitions
in preparation for a future patch which will use them.

During DF C-State, Perfmon counters outside of range 1D700-1D7FF will
encounter SLVERR affecting xGMI performance monitoring. PerfmonCtr[7:4]
is being added to avoid SLVERR during read since it falls within this
range. PerfmonCtl[7:4] is being added in order to arm PerfmonCtr[7:4].
Since PerfmonCtl[7:4] exists outside of range 1D700-1D7FF, DF routines
will be enabled to opportunistically re-arm PerfmonCtl[7:4] on retry
after SLVERR.
