fbdev: omapfb: Fix __be32 sparse warning in panel_enabled()

Browse Source 
This commit resolves a sparse warning in panel_enabled() by explicitly
reading the display status into a __be32 variable. It then converts this
value to CPU endianness using __be32_to_cpu() before checking the bits.
This should fix this sparse warning:
../omapfb/displays/panel-sony-acx565akm.c:218:23: sparse: sparse: cast to restricted __be32
