ASoC: SOF: Introduce function sof_of_machine_select

Browse Source 
From current design in sof_machine_check the SOF can only support
ACPI type machine.

In sof_machine_check if there is no ACPI machine exist, the function
will return -ENODEV directly, that's we don't expected if we do not
base on ACPI machine.

So we add a new function named sof_of_machine_select that we can pass
sof_machine_check and obtain info required by snd_sof_new_platform_drv.
