Subject: [PATCH -next] drm/bridge: cdns: Remove set but not used variable 'bpp'

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/bridge/cdns-dsi.c: In function 'cdns_dsi_bridge_enable':
drivers/gpu/drm/bridge/cdns-dsi.c:986:6: warning:
 variable 'bpp' set but not used [-Wunused-but-set-variable]

It never used since introduction.
