Enable open source GPU support

Browse Source 
Enable open source GPU support for Mali Utgard GPUs (lima driver) and
Mali Midgard and Bifrost GPUs (panfrost driver).
The support is enabled by:
- enabling DRM kernel CONFIGs
- enabling lima, panfrost and kmsro in Mesa
- disabling the specific mali driver overrides in sunxi-mali.inc
To enable open source mainline graphics support just add the following
line in your local.conf:

MACHINEOVERRIDES .= ":use-mailine-graphics"

Please note that some machines may need a bigger CMA value to be able to
start Weston. To do that, add e.g. "cma=128M" to the kernel parameters.
