This commit enables the RK3399 HDMI TX, which is very similar to the
one found on the RK3288. As requested by Simon, this splits the HDMI
driver into a SOC-specific portion (rk3399_hdmi.c, rk3288_hdmi.c) and
a common portion (rk_hdmi.c).
Note that the I2C communication for reading the EDID works well with
the default settings, but does not with the alternate settings used on
the RK3288... this configuration aspect is reflected by the driverdata
for the RK3399 driver.
Having some sort of DTS-based configuration for the regulator
dependencies would be nice for the future, but for now we simply use
lists of regulator names (also via driverdata) that we probe.

To prepare for adding the RK3399 VOP driver (which shares most of its
registers and config logic with the RK3228 VOP), this change refactors
the driver and splits the RK3288-specific driver off.
The changes in detail are:
- introduces a data-structure for chip-specific drivers to register
features/callbacks with the common driver: at this time, this is
limited to a callback for setting the pin polarities (between the
VOP and the encoder modules) and a flag to signal 10bit RGB
capability
- refactors the probing of regulators into a helper function that
can take a list of regulator names to probe and autoset
- moves the priv data-structure into a (common) header file to be
used by the chip-specific drivers to provide base addresses to
the common driver
- uses a callback into the chip-specific driver to set pin polarities
(replacing the direct register accesses previously used)
- splits enabling the output (towards an encoder) into a separate
help function withint the common driver
