usb: gadget: f_uac2: Support multiple sampling rates
A list of sampling rates can be specified via configfs. All enabled
sampling rates are sent to the USB host on request. When the host
selects a sampling rate, the internal active rate (stored in
struct f_uac2) is updated.
The gadget no longer supports only one frequency. Therefore USB strings
corresponding to the clock sources are renamed from specific Hz value to
general names Input clock/Output clock.
Config strings with single value stay compatible with the previous
version.
Multiple samplerates passed as configuration arrays to g_audio module
when built for f_uac2.
