video: fbdev: radeonfb: remove set but not used variable 'hSyncPol'

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

drivers/video/fbdev/aty/radeon_base.c: In function
‘radeonfb_set_par’:
drivers/video/fbdev/aty/radeon_base.c:1653:6: warning: variable
‘hSyncPol’ set but not used [-Wunused-but-set-variable]

It is never used, and so can be removed.
