is not set
This patch does the following,
1. Removes RDT code if CONFIG_RDT_ENABLED flag is
not set.
2. Set the CONFIG_RDT_ENABLED flag only on platforms
that support RDT so that build scripts will automatically
reflect the config.

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.

Upcoming intel platforms can support both L2 and L3
but our current code only supports either L2 or L3 CAT.
So split the MSRs so that we can support allocation
for both L2 and L3.
This patch does the following,
1. splits programming of L2 and L3 cache resource
based on the resource ID.
2. Replace generic platform_clos_array struct with resource
specific struct in all the existing board.c files.

As part of rdt cat refactoring, goal is to combine all rdt
specific features such as CAT under one module. So renaming
rdt resouce specific files such as cat.c/.h to generic rdt.c/.h
files.
