[PATCH 3/3] MIPS: ralink: dts: gardena_smart_gateway_mt7688: Limit UART1

[Stefan Roese]

From: Reto Schneider <reto.schneider@husqvarnagroup.com>

The radio module asserts CTS when its RX buffer has 10 bytes left.
Putting just 8 instead of 16 bytes into the UART1 TX buffer on the Linux
side ensures to not overflow the RX buffer on the radio module side.
