MLK-23116-4 gpu: imx: dpu-blit: Control DPRC gasket shadow enable with dedicated helpers
Call helpers dprc_gasket_shadow_enable/disable() to control
DPRC's gasket(PRG) SHADOW_EN bit so that we may remove
those lines in dprc/prg_configure() which also control the bit.
This patch should be code-change-only, no functional impact.
