[RFCv2 0/8] [media] si4713 DT binding

Hi,

This is the RFCv2 patchset 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
is used 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.

Tested:
* Compilation on torvalds/linux.git:master (based on 52d589a)
* 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)

Changes since RFCv1 (requested by Hans Verkuil):
- splitted the patchset into more patches
- replaced dev_info with dev_dbg for missing regulators
- check for ENOSYS value from devm_gpiod_get (disabled GPIOLIB)
