msm: mdss: hdmi: do not toggle power for HDMI modules
Do not toggle the power for HDMI modules during continuous splash
since the power would have been enabled in the bootloader.
Toggling power during handoff can leave the core in a bad state
especially when scrambling is enabled for 4K HDMI modes.
