Subject: [PATCH v2 1/2] arm64: dts: qcom: sdm845-sony-xperia-tama: Correct
 uart instances

From: Petr Hodina <petr.hodina@...tonmail.com>

Change the uart instances:
- uart6 is for bluetooth
- uart9 is for serial console (available on the uSD pinout)

Most OSes assume serial0 is for console UART. Bluetooth interface uses
UART interface. uart6 is standard debug console and uart9 bluetooth on
SDM845 devices.
