sway fails to start on rockchip devices with mesa 24.2.0-rc2

Tried mesa 24.2.0 for the first time today but unfortunately sway no longer starts:

The culprit seems to be that HAVE_KMSRO is never defined in: https://gitlab.freedesktop.org/mesa/mesa/-/blob/23b0798551bc32f2885ac5016b7ba8584c8c6a2e/src/gallium/targets/dri/dri_target.c#L252

Usual set of gallium drivers that do define HAVE_<driver> does not include kmsro: https://gitlab.freedesktop.org/mesa/mesa/-/blob/23b0798551bc32f2885ac5016b7ba8584c8c6a2e/meson.build#L161-L164

Not really sure but perhaps it should rely on GALLIUM_KMSRO define instead, the only one available with kmsro: https://gitlab.freedesktop.org/mesa/mesa/-/blob/23b0798551bc32f2885ac5016b7ba8584c8c6a2e/src/gallium/winsys/kmsro/drm/meson.build#L18
