video: fbdev: mxsfb: remove set but not used variable 'line_count' 

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

drivers/video/fbdev/mxsfb.c: In function 'mxsfb_restore_mode':
drivers/video/fbdev/mxsfb.c:633:11: warning:
 variable 'line_count' set but not used [-Wunused-but-set-variable]

It's never used since introduction in commit f0a523b5e5 ("video: Add i.MX23/28
framebuffer driver") and can be removed.
