drm/msm: Fix a7xx per pipe register programming

GEN7_GRAS_NC_MODE_CNTL was only programmed for BR and not for BV pipe
but it needs to be programmed for both.

Program both pipes in hw_init and introducea separate reglist for it in
order to add this register to the dynamic reglist which supports
restoring registers per pipe.
