This commit adds support for this, autodetecting AIF1 vs AIF2 based on BIOS tables. While at it also add support for SSP2-AIF2 setups, as that requires only minimal extra code on top of the code adding SSP0-AIF1 / SSP0-AIF2 support. Note this code is all copy-pasted from bytcr_rt5640.c. I've looked into merging the 2 machine drivers into 1 to avoid copy-pasting, but there are enough subtile differences to make this hard *and* with all the quirks the machine driver already is full with if (variant-foo) then ... else ... constructs adding more of these is going to make the code unreadable.
