Fix pixel clock value overflow when reading from the

panels; wrong frame rates were leading to low bandwidth

The DSI clocks need to sourced out of the correct DSI PLL depending
on the h/w configuration. The current assumption is that the
clk_set_parent operation on DSI branch clocks is necessary for
targets which support 2 DSI PLLs. However, there is a possibility
that the DSI clock source needs to be set even for single DSI
targets if the clock driver implements multi-parent based
approach for DSI RCG clock structures. Add change to take care
of this.

-> Eary touch event: Turns on clock and schedule the off

-> Kickoff thread: Leaves the clock on
-> Second touch event: Reschedule the clock off workque
The second touch event call scheduling the clock off

4 vysnc cycle. The clocks will be turned off for such
