for read poll timeouts. This allows for easy overriding
of the function, if necessary.

This change allows dynamic refresh trigger to sw trigger
and mdp intf flush. With this we can make sure that DSI
timing/clock update and mdp intf timings are updated in
one vsync.

Add support to read cphy boolean flag from panel dtsi
and configure DSI PHY registers accordingly. Update the
bit/byte clock calculation according to cphy specifications.
Update clock parents so that the relevant divider blocks
are configured to support cphy.

DSI PLL is tightly coupled with DSI PHY. This change removes
separate DSI pll driver and makes DSI pll as a subnode to DSI
PHY which is an accurate way of representation. In addition, this
change adds support for 5nm DSI ctrl and PHY revisions and adds
DSI pll support for 5nm. Remove support for older DSI pll revisions
such as 7nm, 10nm, 14nm, 20nm, 28nm.
