U-boot still uses the old compatible "brcm,bcm2835-pl011" for the UARTs. The Pi
4B has additional UARTs 2-5 which need this compatible as well otherwise u-boot
won't load with something like 'dtoverlay=uart4'.

  UBUNTU: SAUCE: arm: dts: Clarify the need for "brcm,bcm2835-<foo>"
  UBUNTU: SAUCE: arm: dts: Add 'brcm,bcm2835-pl011' for compatible for
    uart2-5
