Own I2C locking is needed due to two special reasons:
1) Chips uses multiple register pages/banks on single I2C slave.
Page is changed via I2C register access.
2) Chip offers muxed/gated I2C adapter for tuner. Gate/mux is
controlled by I2C register access.
Due to these reasons, I2C locking did not fit very well.

dib8000_write_word(state, 1947, reg | (1<<14) | ((upd_demod_gain_period >> 16) & 0xFF));
So, it should be declared as u32.

Add media controller support to the adv7180 driver by registering a media
entity instance for it as well as implementing pad ops for configuring the
format.
As there currently don't seem to be any users of the video ops format
operations those are removed as well in this patch.
Also set the V4L2_SUBDEV_FL_HAS_DEVNODE flag for the subdevice so it is
possible to create a subdevice device node.
Since the driver now depends on VIDEO_V4L2_SUBDEV_API all drivers which
select the driver need to depend on that symbol as well.

The ad7180 has multiple register pages which can be switched between by
writing to a register. Currently the driver manually switches between pages
whenever a register outside of the default register map is accessed and
switches back after it has been accessed. This is a bit tedious and also
potential source for bugs.
This patch adds two helper functions that take care of switching between
pages and reading/writing the register. The register numbers for registers
are updated to encode both the page (in the upper 8-bits) and the register
(in the lower 8-bits) numbers.
Having multiple pages means that a register access is not a single atomic
i2c_smbus_write_byte_data() or i2c_smbus_read_byte_data() call and we need
to make sure that concurrent register access does not race against each
other.
