[PATCH] drm/rockchip: dsi: Remove the unused function dsi_update_bits()

[Jiapeng Chong]

The function dsi_update_bits() is defined in the dw-mipi-dsi-rockchip.c
file, but not called elsewhere, so delete this unused function.

drivers/gpu/drm/rockchip/dw-mipi-dsi-rockchip.c:367:20: warning: unused function 'dsi_update_bits'.
