linux-firmware/i915: Fix Corrupted GuC files.

linux-firmware/i915: Fix Corrupted GuC files.

For some reason these 2 files got corrupted
when propagating the release to this repository.

i915 firmware got first release at:
https://01.org/linuxgraphics/downloads/firmware
then propagated to linux-firmware.git.

The version on 01.org are the right ones.

This issue has been identified by Jason. He
noticed that GuC image from linux-firmware.git
wasn't getting loaded on his Kabylake, while
the version on 01.org was working propertly.

In a further review I identified that also GuC
image for Broxton faced a similar issue. All other
files on i915 are the proper one matching with
the ones released on 01.org.
