What if only BR2_PACKAGE_MESA3D_VULKAN_DRIVER_FREEDRENO is set ?

MESA3D_GALLIUM_DRIVER_FREEDRENO_KMDS can be set without
BR2_PACKAGE_MESA3D_GALLIUM_DRIVER_FREEDRENO enabled.

Maybe MESA3D_GALLIUM_DRIVER_FREEDRENO_KMDS needs to be renamed ?

Something like MESA3D_FREEDRENO_KMDS? (without "Gallium word).

KMDS stand for "kernel-mode drivers" for freedreno gallium and vulkan driver

Best regards,
Romain
