msm_fb: HDMI: Update HPD logic to address HDMI PLL related issues
In the current implementation, the regulators pertaining to the
HDMI core are turned off/on as part of the configuration of the
HDP circuitry. As a result, the regulator that powers the HDMI
PLL is turned off before the HDMI clocks on the PLL are disabled.
This might lead to the PLL not getting locked when it is re-enabled.
This change turns on and off the regulators and clocks in proper
sequence.
