usb: gadget: f_uac1: 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 is updated.
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_uac1.
