drm/omap: Remove set but not used variable 'tclk_trail' 

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

drivers/gpu/drm/omapdrm/dss/dsi.c: In function dsi_proto_timings:
drivers/gpu/drm/omapdrm/dss/dsi.c:3562:46: warning: variable tclk_trail set but not used [-Wunused-but-set-variable]

It is not used since commit 9960aa7cb5 ("drm/omap:
move omapdss & displays under omapdrm")
