cache configuration.
This patch creates a generic infrastructure for
RDT resources instead of just L2 or L3 cache. This
patch also fixes L3 CAT config overwrite by L2 in
cases where both L2 and L3 CAT are supported.

There can be times when user unknowinlgy enables
CONFIG_CAT_ENBALED SW flag, but the hardware might
not support L3 or L2 CAT. In such case software can
end up writing to the CAT MSRs which can cause
undefined results. The patch fixes the issue by
enabling CAT only when both HW as well software
via the CONFIG_CAT_ENABLED supports CAT.
The patch also address typo with "clos2prq_msr"
function name. It should be "clos2pqr_msr" instead.
PQR stands for platform qos register.

rdt resouce specific files such as cat.c/.h to generic rdt.c/.h
files.
