arm64: dts: mt8173: Use real clock for UARTs
We used to use a fixed rate clock for the UARTs. Now that we have clock support we can associate the correct clocks to the UARTs and drop the 26MHz fixed rate UART clock. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Signed-off-by: Matthias Brugger <matthias.bgg@gmail.com>
