Martin Jansa e811912fae raspberrypi-firmware: upgrade to latest to fix vc4-fkms 
* with 4.19.66 kernel the vc4-fkms no longer works, because it doesn't
  get any usable modes from firmware

* this behavior was introduced probably in one of following changes:
  38e81f25e6
  https://github.com/raspberrypi/linux/pull/3082
  https://github.com/raspberrypi/linux/pull/3110
  66bafab005

* without this fix:
root@rpijama:~# cat /proc/device-tree/soc/firmwarekms@7e600000/status
okay

root@rpijama:~# modeprint vc4

Ok

* tested on raspberrypi3 B
  weston works fine
  qtbase-examples tested with:
  /usr/share/examples/opengl/cube/cube -platform eglfs

* the same issue is now in warrior, after someone tests on raspberrypi4
  it would be good to backport this to warrior as well
