[gpu] weston fails to start using 5.15 kernel

[otavio]

          @thochstein this seems to regress with 5.15 kernel. I am using varscite SOMs which are still on 5.15.60 kernel. weston refuses to start

Yes, please upgrade https://github.com/Freescale/kernel-module-imx-gpu-viv/blob/master/kernel-module-imx-gpu-viv-src/hal/kernel/inc/gc_hal_version.h#L67 and see if it helps.

Oh, sorry, I did forget to upgradekernel-module-imx-gpu-viv, will do it now.

FWIW #1687 fixed this problem. Thanks @thochstein
