On most of the Amlogic SoCs, the first UART controller in the "Everything-Else"
power domain has 128bytes of RX & TX FIFO, so add an optional property to describe
a different FIFO size from the other ports (64bytes).

This adds a property in the bindings, reads the property from the driver and updates
the DT with the new property.

Changes since v1:
- switched to a more generic "fifo-size"

Neil Armstrong (3):
  dt-bindings: serial: amlogic,meson-uart: add fifo-size property
  tty: serial: meson: retrieve port FIFO size from DT
  arm64: dts: meson: set 128bytes FIFO size on uart A
