Rodrigo Vivi 5a7595e80b 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

Rodrigo Vivi b693dacc8b linux-firmware: Add i915 DMC firmware
DMC provides additional graphics low-power idle states. It provides
capability to save and restore display registers across these low-power
states independently from the OS/Kernel.

This is the first release of DMC firmware for Skylake platforms.

skl_dmc_ver1.bin is a symbolik link to latest recommended minor release.
This major version will be just upgraded on code when it is required
software changes for API/ABI compatibility.
