video: sprdfd: disable ESD feature

The problem that the screen had been changed to block was reported at
some targets. I'm not sure but it might be related with ESD feature of
sprdfd driver, so as workaround, disable ESD feature.

And add some #ifdef to avoid below build errors.

drivers/built-in.o: In function `sprd_enable_vblank':
/home/pub/git/public/tm1_tizen_3.0/linux-3.10-sc7730/drivers/gpu/drm/sprd/sprd_drm_irq.c:265: undefined reference to `panel_esd_enable'
