Gcc report unused-variable warning as follows:

drivers/video/backlight/cr_bllcd.c:62:6: warning:
 unused variable 'intensity' [-Wunused-variable]
   62 |  int intensity = bd->props.brightness;
      |      ^~~~~~~~~

After commit 24d34617c24f ("backlight: cr_bllcd: Introduce
gpio-backlight semantics"), this variable is never used, this
commit removing it.

Fixes: 24d34617c24f ("backlight: cr_bllcd: Introduce gpio-backlight semantics")
