drm: gma500: fix logic error
commit 67a3b63a54cbe18944191f43d644686731cf30c7 upstream.
gcc-8 points out a condition that almost certainly doesn't
do what the author had in mind:
drivers/gpu/drm/gma500/mdfld_intel_display.c: In function 'mdfldWaitForPipeEnable':
drivers/gpu/drm/gma500/mdfld_intel_display.c:102:37: error: bitwise comparison always evaluates to false [-Werror=tautological-compare]
This changes it to a simple bit mask operation to check
whether the bit is set.
Fixes: 026abc333205 ("gma500: initial medfield merge")
