ASoC: Intel: avs: New board registration routines

To support multiple instances of the same card utilize
PLATFORM_DEVID_AUTO when registering new platform devices. This
adaptation is also an opportunity to streamline the devices
registration - avs_register_board().

All the new functions are equivalents of the existing ones apart from
adjusting platform_device_register_data() call with PLATFORM_DEVID_AUTO
and code size reduction given the presence of unified register function.
Follow up changes will complete the transition and cleanup the duplicate
members.
