dmaengine: idxd: Add descriptor definitions for 16 bytes of pattern in memory fill operation

Browse source

The memory fill operation (0x04) can fill in memory with either 8 bytes
or 16 bytes of pattern. To fill in memory with 16 bytes of pattern, the
first 8 bytes are provided in pattern lower in bytes 16-23 and the next
8 bytes are in pattern upper in bytes 40-47 in the descriptor. Currently
only 8 bytes of pattern is enabled.

Add descriptor definitions for pattern lower and pattern upper so that
user can use 16 bytes of pattern to fill memory.
