sunxi: video: Give hotplug-detect (hpd) signal some time to show up
When using a hdmi powered hdmi to vga dongle, and cold booting a sunxi
device, the hpd detect code would not see the dongle (until a warm reboot),
because the dongle needs some time to boot.
Testing has shown that this dongle needs 213ms to respond on a cold boot,
so wait up to 300ms for a hpd signal to show up before giving up.
