sound: Add RT5677 codec driver (used on Ryu/A44)
I2S mode, bits, format, etc. is done, and a slam of
initial codec reg values (same as kernel driver) is done.
RT5677 support will be enabled in a follow-on CL.
Builds, runs, hear a bleep from the HP output!
But still no sound from mono speaker on P0/P1.
Need to debug speaker amp settings?
Note that this sets up I2S2 as master for the
speaker amp on Ryu (AD4567). Should go away when
Ryu P3 is ready (speakers are on PDM). May need more
tweaks for P3.
