dsi_panel: remove avdd_enable and avee_enable gpios.

Browse source 
hange the default output voltage through I2C bus at XBL. And store the default
value to EEPROM. So we can nod make I2C operation at kernel.
Only pull up/down gpio to enable/disable regulator.
So use gpio regulator to control avee and avdd.
