Subject[RFC 0/2] [media] si4713 DT binding

This is an RFC patch adding DT support to the si4713 radio transmitter i2c
driver. The changes can be summarized as follows:

* Move regulator information back into the driver. The regulators needed are
documented in the chip and have nothing to do with boarddata. Instead
devm_regulator_get_optional and errors are handled quite loosely now.
Maybe the USB driver should provide dummy regulators.
* GPIO handling is updated to gpiod consumer interface, resulting in a driver
cleanup and easy DT handling
* The driver is updated to use managed resources wherever possible

So much about the nice stuff. But there is also

* Instantiation of the platform device from the i2c (sub-)device. Since DT
is not supposed to contain linuxisms the device is a simple i2c node
resulting in the i2c probe function being called. Thus registering the main
v4l device must happen from there.

* Compilation on torvalds/linux.git:master
* Booting in DT mode
* Some simply driver queries using v4l2-ctl

Not tested:
* The USB driver, since I do not own the USB dongle
* The legacy platform code (only DT boot has been tested).
(The legacy platform code is supposed to removed in the near future anyways)
