HW bug in third party PCIE IP - PCIE datapath hangs when there are
more than 28 outstanding requests on data backbone for x1 controller.
Suggested SW WAR is to limit reorder_depth_limit to 16 for
PCIE 1W/2AW/3W clients.

Memory clients are divided in to ISO/NonISO/Order/Unordered/Low
BW/High BW. Based on the client types, HW team recommends, different
memory ordering settings, IO coherency settings and SMMU register settings
for optimized performance of the MC clients.
For example ordered ISO clients should be set as strongly ordered and
should bypass SCF and directly access MC hence set as
FORCE_NON_COHERENT. Like this there are multiple recommendations
for all of the MC clients.
This change sets all these MC registers as per HW spec file.

Due to a hardware bug PVA may perform memory transactions which
cause coalescer faults. This change works around the issue by
disabling coalescer for PVA0RDC and PVA1RDC.

Force memory transactions from viw and viflar/w as non-coherent from
no-override. This is necessary as iso clients shouldn't use coherent
path and stage-2 smmu mappings won't mark transactions as non-coherent.
For native case, no-override works. But, not for virtualization case.

Client order id reset values are incorrectly and'ed with
mc_client_order_id macro, which resulted in getting reg value as
always zero. Updated mc_client_order_id macro to avoid and'ing outside
the macro, to take the reg value and update specific bit field
as necessary.
