msm: mdss: fix to update the configuration for display related GPIOs

Browse source 
After commit dbe80b7cc96a1f3f23246552fbd2352f334fa857 ("ARM: dts: msm:
remove gpio output settings in dsi pinctrl") driver is no longer
defining in the pinctrl the gpios as output high configuration;
so driver now has to explicitly configure gpio output direction.
This change add the settings in the driver to configure the gpio
as output pin, fixing panel issues when booting-up with
continuous splash disabled.
