ASoC: Intel: avs: Add basefw runtime-parameter requests

Each module may expose a range of runtime parameters. For basefw,
implement handlers for: FIRMWARE_CONFIG, HARDWARE_CONFIG and
MODULES_INFO. These are used by driver to dynamically allocate resources
in respect to platform details, reducing number of hardcodes and code
duplications that would otherwise be needed to be defined within the
driver code.
