6.6-stable review patch. If anyone has any objections, please let me know.
------------------
From: Quentin Schulz quentin.schulz@cherry.de
commit 2db7d29c7b1629ced3cbab3de242511eb3c22066 upstream.
UART0 pinmux by default configures GPIO0_B5 in its UART RTS function for UART0. However, by default on Haikou, it is used as GPIO as UART RTS for UART5.
Therefore, let's update UART0 pinmux to not configure the pin in that mode, a later commit will make UART5 request the GPIO pinmux.
