ASoC: Updates for v4.21

Not much work on the core this time around but we've seen quite a bit of
driver work, including on the generic DT drivers.  There's also a large
part of the diff from a merge of the DaVinci and OMAP directories, along
with some active development there:

 - Preparatory work from Morimoto-san for merging the audio-graph and
   audio-graph-scu cards.
 - A merge of the TI OMAP and DaVinci directories, the OMAP product line
   has been merged into the DaVinci product line so there is now a lot
   of IP sharing which meant that the split directories just got in the
   way.  This has pulled in a few architecture changes as well.
 - A big cleanup of the Maxim MAX9867 driver from Ladislav Michl.
 - Support for Asahi Kaesi AKM4118, AMD ACP3x, Intel platforms with
   RT5660, Meson AXG S/PDIF inputs, several Qualcomm IPs and Xilinx I2S
   controllers.
