ASoC: SOF: core: Module parameter updates

Merge series from Peter Ujfalusi <peter.ujfalusi@linux.intel.com>:

Add new debug only parameters to override the default IPC and boot
timeout, these are only available if CONFIG_SND_SOC_SOF_DEBUG is
enabled, only for developers.

The second patch moves the firmware, topology name/path and IPC
version overrides from acpi/pci/of platform code to core and markes
the platform parameters deprecated, to be removed in few kernel
cycles.
There is really no point of duplicating these overrides as they
are not platform dependent.
