Sankeerth Billakanti a457a0ada9 disp: msm: dp: set ctrl power_on flag when link clock is on ...

While running DP simulation script for stability and the rare
occasions when link clock fails to enable, the ctrl power_on
flag is wrongly set indicating the link is powered on. This
flag is used in the ctrl sub-module to check that the link
clock is on before accessing the registers powered by the
link clock. When this flag is wrongly set, the link registers
are accessed while processing the cable disconnect to cause a
NOC error.

The change will ensure the power_on flag is set when the link
clock is on so that the access to registers in the link clock
domain can be correctly filtered by the power_on flag.
