linux-firmware: New minor DMC release for Skylake.

Following additions:
1. The DE_RRMR and DE_GUCRMR register bits are set before the restore of
the registers to mask the flip done, etc. Once all the registers are
restored, these registers are restored.
2. The pipe interrupt registers are restored only after the plane has
been enabled.
3. Naming of the file changed from .5 to .16 to make it two decimal
points for increased number of versions that can be supported.
4. DC 5 and 6 count locations are in the below mentioned offsets
DC3_DC5_COUNT                  80030
DC5_DC6_COUNT                  8002C
