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

[Jiapeng Chong]

The function dsi_read is defined in the dw-mipi-dsi-rockchip.c file, but
not called elsewhere, so remove this unused function.

drivers/gpu/drm/rockchip/dw-mipi-dsi-rockchip.c:362:19: warning: unused function 'dsi_read'.
