On Waipio target, periph top0 block has been removed from mdp top
register block. This creates a hole in the accessible register space
and can lead to NOC errors. In addition, accessing register offset
for invalid dedicated concurrent write back can lead to NOC errors.
This change adds support for indicating if the periph block has been
removed and splitting the mdp top register block into two for reg dump.
In addition, it only registers valid dcwb to be reg dumped by
adding a dcwb count.

For DPHY, DSI byte clock is used to derive the byte interface clock through
a DIV_2 divider. While setting the rate for byte interface clock, if the byte
clock rate is odd the recalculation of byte interface clock will fail. This
can further lead to recalculation of byte clock and result in unexpected
value for byte clock. The change ensures that for DPHY, the byte clock rate is
always even to avoid such issues.

DP driver maintains the number of allocated DSCs per stream for managing
the availability of DSC blocks for each stream. In the current driver,
if there are errors in the disable path, it is possible for the refcount
to go negative thereby affecting the availability of DSC blocks in

This change fixes the refcount logic by making sure the DSC count in the
