disp: msm: Parsing and store panel's 0xDA register info

Browse source 
Since ALS sensor's Firmware needs to keep track the PWM duty cycle of
each panels' version, therefore the panels' register 0xDA will be used
to identify the PWM duty cycle programmed in each panels' version.
The new /sys/class/drm/card0-DSI1/panelRegDA sysfs will be created,
and it will show the panel's 0XDA reg information.
