gooseberry_a721: Set display mode to hdmi

Since the gooseberry is a board stripped from a tablet, its fex file assumes
an lcd is present, but on the gooseberry non is connected, to lets activate
the hdmi output by default.

And for whom has heard me complain before that the hdmi on my gooseberry was
not working, this was a cable issue. I already suspected this as I had only
1 cable with a mini hdmi connector. I ordered a new one and now the issue is
gone.

gooseberry_a721: Enable usb2-controller at boot

For some reason the original fex has usb_host_init_state set to 0 for usbc2,
causing it to start with its USB-port power powered down.

This causes any attached devices (the realtek wireless card to be precise)
to not get detected, and the kernel-module to not be auto-loaded.

Manually modprobing the driver works around this, as it causes a bus scan
which powers up the port. But manual modprobing should be necessary, usb is
a plug and play bus afterall. Setting usb_host_init_state to 1 removes the
need for the manual modprobe, now Linux will automatically find the device
and udev will automatically load the driver.
