[OE-core] [PATCH] mesa-lima: Add support for mesa for Mail-4xx GPUs

[Alexander Kanavin]

The status of the driver is described here:
https://www.phoronix.com/scan.php?page=news_item&px=Lima-DRM-Driver-Mainline-V2

Considering the kernel DRM driver is not yet mainlined, and mesa
driver is also developed separately, and the developer says:
"Qiang continues to work on the out-of-tree Lima Mesa driver, which he
says isn't yet ready for daily usage but can run simple tests like the
KMS cube and glmark2."
I think this shouldn't  go to oe-core yet. Once this is in mainline
mesa and kernel, it will be available 'automatically' through version
updates, until then the pieces belong in a suitable BSP layer, I
think.
