Add the new DAI block for I2S2 which is used for HDMI audio.

Signed-off-by: Marcus Cooper <redacted>

queued for 4.17, thanks!

Please note that HDMI I2S has usable 4 I2S lanes, since HDMI
supports 8 channel audio. As Marcus said, other blocks probably
support them too, they are just not wired out on pins.

I've dropped those patches for now.

Should we change compatible for HDMI?

I guess, another way of doing things if they are strictly identical
but for the number of lanes they support would be to add a DT property
for that number of lanes.

That's fine...I'll look into adding a dt property and how we would map
channels to lanes.
Do you know of any examples?,

Grepping for of_property_read_u32 should give you plenty of examples :)
