drm/gma500: remove set but not used variable 'channel_eq'

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

drivers/gpu/drm/gma500/cdv_intel_dp.c: In function cdv_intel_dp_complete_link_train:
drivers/gpu/drm/gma500/cdv_intel_dp.c:1596:7: warning: variable channel_eq set but not used [-Wunused-but-set-variable]

It is never used, so remove it.
