drm/gma500/oaktrail_lvds_i2c: Remove unused variables 'tmp'

Fixes the following W=1 kernel build warning(s):

 drivers/gpu/drm/gma500/oaktrail_lvds_i2c.c: In function ‘get_clock’:
 drivers/gpu/drm/gma500/oaktrail_lvds_i2c.c:69:11: warning: variable ‘tmp’ set but not used [-Wunused-but-set-variable]
 drivers/gpu/drm/gma500/oaktrail_lvds_i2c.c: In function ‘get_data’:
 drivers/gpu/drm/gma500/oaktrail_lvds_i2c.c:83:11: warning: variable ‘tmp’ set but not used [-Wunused-but-set-variable]
