sunxi-mali-mainline: add support for arm64 and r8p1 blob version

Blobs for arm64(aarch64) and r8p1 version are now available at Bootlin
Github.

So:
- Bump version to latest commit:
For arm64 architecture and r8p1 version.

git shortlog --no-merges cb3e8ece9b2c3a70cbeb3204cd6f30eceaa32023..
Giulio Benetti (1):
      Reorder folders splitting includes and libraries.

Maxime Ripard (6):
      Move binaries to an arch subfolder
      Make x11 binaries path consistent
      Add r6p2 arm wayland blobs
      Add r6p2 arm64 blobs
      Add r8p1 fbdev blobs
      Add r8p1 arm64 fbdev blobs

- Add support for them also under arm64(aarch64) architecture copying the
right blobs according to architecture(arm or arm64) checking if BR2_arm
or BR2_aarch64 is enabled.
Only BR2_arm needs to provide BR2_ARM_EABIHF, so check must be done only
in that case.
- Mali-blobs repository folder layout has been reordered, so modify path
when copying headers and libraries.
- When copying libraries copy only *.so* files to avoid useless files to
end into target folder.
