- Added app PLL config functions - previously were in sw_usb_audio

Browse Source 
- Use app PLL for sync mode
- Use app PLL on xcore.ai devices by default (unless ADAT or SPDIF receive enabled) 
- Added XUA_USE_APP_PLL (which is default 1)
- Some tidy of xua_conf_default.h
- Added DEFAULT_MCLK define
