meta-agl-bsp: Update i.MX8MQ EVK support for latest dunfell

The layer updates to go to the latest 3.1.4 Yocto dunfell release
broke the imx8mqevk and imx8mqevk-viv builds, though for different
reasons.

imx8mqevk fixes:
- Remove the now upstreamed etnaviv kernel patches that had been
  backported by Walter.
- Turn off btrfs support in the linux-fslc-imx kernel configuration.
  This is required due to meta-freescale having a 5.4 kernel new
  enough to need a lttng-modules fix for btrfs that has not yet been
  backported from the Yocto master branch to dunfell.
- Update the PREFERRED_VERSION over-rides in agl_imx8mqevk.inc to
  match the new versions of libdrm and gstreamer in poky.

imx8mqevk-viv fixes:
- Add weston_8.0.0.imx.bbappend to work around the broken addition
  of a PACKAGECONFIG_remove of "x11 wayland" in the recipe in
  meta-freescale.  Upstream will be engaged to drive getting the
  change reverted.

-Subject: [PATCH] drm/etnaviv: fix TS cache flushing on GPUs with BLT engine
-
-As seen in the Vivante kernel driver, most GPUs with the BLT engine have
-a broken TS cache flush. The workaround is to temporarily set the BLT
-command to CLEAR_IMAGE, without actually executing the clear. Apparently
-this state change is enough to trigger the required TS cache flush. As
-the BLT engine is completely asychronous, we also need a few more stall
-states to synchronize the flush with the frontend.
