Add support for configuring the Display Parallel Interface block
to output YUV444 8/10 bits, YUV422 10/12 bits (8 bits support is
already present), BGR 8-bits, and RGB 10-bits.
The enablement of the various additional output formats in SoCs
platform data will be done in a different change.

In preparation for adding support for additional color formats,
add local helpers to map media bus format parameters to this
driver's bit_num, channel_swap and color_format.
This commit brings no functional changes.

In preparation for adding support for an additional color format,
convert the format conditional in mtk_dpi_config_color_format()
to a switch.
This also makes the concept of RGB being the default color format
a little more human readable.

In preparation for moving the common bits of this driver, merge the
contents of mtk_hdmi_output_init in mtk_hdmi_register_audio_driver
function to aggregate all of the initial audio setup together in
the same function and to make it clear that all of the setup that
is performed in mtk_hdmi_output_init is specifically related only
to audio and not video.

Move the CEC device parsing logic to a new function called
mtk_hdmi_get_cec_dev(), and move the parsing action to the end
of mtk_hdmi_dt_parse_pdata(), allowing to remove gotos in this
function, reducing code size and improving readability.

Change error prints to use dev_err_probe() instead of dev_err()
where possible in function mtk_hdmi_dt_parse_pdata(), used only
during device probe.
While at it, also beautify some prints.

In preparation for splitting common bits of this driver, moving
the hdmi_rec_n_table struct array, and the hdmi_recommended_n(),
hdmi_mode_clock_to_hz(), hdmi_expected_cts() functions, add one
function called mtk_hdmi_get_ncts() that sets both N and CTS in
a single call.

In preparation for splitting common bits of this driver, move the
audio params (codec, sample rate/size, input type, i2s format, etc)
selection to a new function called mtk_hdmi_audio_params().
While at it, also rename "hdmi_params" to "aud_params" both to match
the mtk_hdmi struct member name and to clarify that those parameters
are for HDMI Audio and not for HDMI Video configuration.

As a cleanup, and in preparation for splitting common bits of this
driver, disgregate the code in function mtk_hdmi_audio_set_param()
to the beginning and end of function mtk_hdmi_audio_hw_params().
In a later commit, the hw_params callback function will also be
disgregated so that the code will get two functions: one that
performs the generic hdmi_audio_param copy, and one that performs
IP specific setup, both of which will be called in the callback,
allowing all of the non IP version specific code to get moved in
a common file.

Now that all of the mtk_hdmi subdrivers are a platform driver on
their own it is possible to remove the custom init/exit functions
in this driver and just use the module_platform_driver() macro.
While at it, also compress struct of_device_id entries and remove
stray commas in mtk_hdmi_driver assignments.

In preparation for adding a driver for the new HDMIv2 IP, and
before splitting out the common bits from the HDMI driver,
change the mtk_hdmi_ddc driver from being registered from the
HDMI driver itself to be a module_platform_driver of its own.
With this change, there are no more users of the mtk_hdmi.h header
so, while at it, also remove it.

In preparation for adding a driver for the new HDMIv2 IP, and
before splitting out the common bits from the HDMI driver, change
the mtk_cec driver from being registered from the mtk_hdmi driver
itself to be a module_platform_driver of its own.
Besides being a cleanup, this also allows build flexibility by
allowing to compile the CECv1 driver only when needed (for example,
this is not needed nor used in HDMIv2 configurations).

Use syscon_regmap_lookup_by_phandle_args() which is a wrapper over
syscon_regmap_lookup_by_phandle() combined with getting the syscon
argument. Except simpler code this annotates within one line that given
phandle has arguments, so grepping for code would be easier.
There is also no real benefit in printing errors on missing syscon
argument, because this is done just too late: runtime check on
static/build-time data. Dtschema and Devicetree bindings offer the
static/build-time check for this already.
