XUF216 -> XUF316 sw_usb_audio

[dtns]

When porting from XU2 to XU3, is the CS2100 PLL still required or can now the internal PLL be used for using ADAT I/O + I2S/TDM I/O simultaneously?
Cirrus Logic has marked their lineup of the CS2xxx as end of life and I would like to have a future-proof(er) solution.

When using xcore.ai, you can indeed use the application PLL to recover the master clock from an ADAT input, so the CS2100 PLL is not required. In sw_usb_audio, this is enabled by default in lib_xua using the define XUA_USE_SW_PLL.
