ASoC: SOF: Intel: disable IMR boot when resuming from ACPI S4 and S5 states

The IMR was assumed to be preserved when suspending to S4 and S5
states, but community reports invalidate that assumption, the hardware
seems to be powered off and the IMR memory content cleared.

Make sure regular boot with firmware download is used for S4 and S5.
