From current design in sof_machine_check and snd_sof_new_platform_drv,
the SOF can only support ACPI type machine.

1. 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.

2. In snd_sof_new_platform_drv the component driver need a driver name
to do ignore_machine, currently the driver name is obtained from
machine->drv_name, and the type of machine is snd_soc_acpi_mach.

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.
