drm/panel/panel-sitronix-st7701: Adjust porch control bitfield name 



Define DSI_CMD2_BK0_PORCTRL_VBP_MASK and DSI_CMD2_BK0_PORCTRL_VFP_MASK
and move the vertical back and front porch calculation from macros into
the st7701_init_sequence() function, so it is clear what this does.

No functional change.
