Add a flag to wm_adsp_power_up() that indicates whether it should attempt
to find and load firmware files.
This is to support DSPs that have built-in firmware that may already have
been patched (for example, by the BIOS). In that case the patch must not
be overwritten because that could corrupt the running firmware.
