Amlogic 32-bit DT updates for v4.21
- support more timers on meson8
- add the stdout-path property on several boards

* tag 'amlogic-dt' of https://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-amlogic:
  ARM: dts: meson: add the clock inputs for the Meson timer
  ARM: dts: meson: add the TIMER B/C/D interrupts
  ARM: dts: meson: consistently disable pin bias
  ARM: dts: meson8b: mxq: add the /chosen/stdout-path property
  ARM: dts: meson8: minix-neo-x8: add the /chosen/stdout-path property
  ARM: dts: meson6: atv1200: add the /chosen/stdout-path property
  dt-bindings: timer: meson6_timer: document the clock inputs
