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.

Changes in v4:
- splits the large change into smaller changes
Changes in v3:
- split into separate drivers for the SOC-specific portion of the driver
- rebase to sjg/next
Changes in v2:
- removed DEBUG from the patch (as was done in our production branches, but missing from the patch-prep branch)
- updated SJG's comment (with a TODO for the RK3288) to reflect the new code structure
