drm/vc4: Fix reduce interrupt timeout 'workaround'

Since flag 'ignore_lcd=0' is set in config.txt, dsi interrupt is
disabled so that interrupt does not occur even when dsi_write is
operated. The waiting time causes a boot delay. So it reduces the
timeout to 100msecs until it is resolved. As a result, the boot delay
has been reduced from 22,000 to 2,200 msecs.
