Description:	The DSA3 specification introduces three new capability

		registers: dsacap[0-2]. User components (e.g., configuration

		libraries and workload applications) require this information

		to properly utilize the DSA3 features.

		This includes SGL capability support, Enabling hardware-specific

		optimizations, Configuring memory, etc.

		The output format is '<dsacap2>,<dsacap1>,<dsacap0>' where each

		DSA cap value is a 64 bit hex value.

		This attribute should only be visible on DSA devices of version

		3 or later.
