This patch adds support for the Analog Devices ADV7611 HDMI receiver.
The adv7611 is quite similar to the adv7604. It has only one instead of four
HDMI inputs and no analog frontend though. Also some register bits have been
shuffled around, but large parts of their register maps are compatible.

The subdev EDID ioctls receive a pad field that must reference an

both fields in the core code instead of duplicating validation in all
drivers.

Currently stk1160_read_reg() uses a stack-allocated char to get the
read control value. This is wrong because usb_control_msg() requires
a kmalloc-ed buffer.
This commit fixes such issue by kmalloc'ating a 1-byte buffer to receive
the read value.
While here, let's remove the urb_buf array which was meant for a similar
purpose, but never really used.
