Subject: [PATCH v5, 11/32] drm/mediatek: split DISP_REG_CONFIG_DSI_SEL setting into another use case

From: Yongqiang Niu <yongqiang.niu@...iatek.com>

Here is two modifition in this patch:
1.bls->dpi0 and rdma1->dsi are differen usecase,
Split DISP_REG_CONFIG_DSI_SEL setting into anther usecase
2.remove DISP_REG_CONFIG_DPI_SEL setting, DPI_SEL_IN_BLS is 0 and
this is same with hardware defautl setting,
