[PATCH RFC 00/12] tda998x updates

As no one responded to the previous round, I'm not spending soo much
time writing up a description of these changes again.  It's also been
quite a long time, so I've forgotten all the details of the changes,
so I'll do my best.

Changes from the previous series include:
- reorder the initial three patches
- change the (now third patch)... I think to increase the size of the
  locked region.
- fix edid parsing for infoframe generation - as was pointed out for
  dw-hdmi, parsing the EDID in get_modes() is incorrect, as that method
  will not be called when an override-edid is in effect.  We need to
  parse the override-edid.  Moreover, infoframe generation should not
  be keyed to whether the monitor is HDMI or not, CEA-861B allows non-
  HDMI to send infoframes.
- only send audio if audio and infoframes are supported.

Otherwise, these are very much like the previous posting of the series,
except rebased upon the mali/hdlcd/tda998x change to remove the
drm_connector_register() call.

It'd be nice to have other tda998x users ack and test these patches,
I've tried to test on Juno, but the Juno situation seems to be a huge
fail.  (HBI0282B completely fails with latest firmware - (a) FPGA image
incompatibilities io_b118 causes all FPGA AMBA devices to vanish, (b)
seems no way to get SCPI support on it - adding the BL0 executable
start address in the SCC registers seems to be incompatible with the
devchip, causing the PLLs to fail.  In discussion with Sudeep over
these issues, but no idea where things are with it at the moment, other
than Sudeep needs to investigate.  All Linaro firmware releases are
broken on HBI0282B.)
