LF-4316 drm/panel: panel-raydium-rm67191: Set DSI mode to 0x0B for RM67199

Without this patch, the driver sets the DSI mode to 0x08 for RM67199,
which means 'command RAM mode' as the panel data sheet indicates.
In that mode, something like screen tearing effect can be seen when
doing page flip test by using modetest.  This patch changes the DSI
mode to 0x0B for RM67199, which means 'video RAM capture mode' and
aligns to the setting of RM67191.
