drm/panel: ili9322: Remove redundant volatle_reg() operation

Browse Source 
The ili9322 driver has a volatile_reg() operation in it's regmap which
always returns false. This is redundant since it is the default in the
regmap core, remove the operation for a trivial code size and performance
improvement.
