[PATCH 1/2] ALSA: hda: intel-dsp-config: Add FLAG_BYT_FIRST / _SECOND defines

[Hans de Goede <hdegoede@redhat.com>]

Instead of hardcording the SST driver having the highest prio, add
FLAG_BYT_FIRST and FLAG_BYT_SECOND defines, which get set like this
when both drivers are enabled:

	#define FLAG_BYT_FIRST               FLAG_SST
	#define FLAG_BYT_SECOND              FLAG_SOF

And when only 1 driver is enabled then FLAG_BYT_FIRST gets set to
the flag for that driver.

This is a preparation patch for making which driver is preferred
configurable through Kconfig.
