drm/bridge: cdns: remove set but not used variable 'nlanes'

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

drivers/gpu/drm/bridge/cdns-dsi.c: In function ‘cdns_dsi_mode2cfg’:
drivers/gpu/drm/bridge/cdns-dsi.c:515:11: warning: variable ‘nlanes’
set but not used [-Wunused-but-set-variable]

It is never used, and so can be removed.
