arm64: dts: qcom: sdm845-tama: Set serial indices and stdout-path

[ Upstream commit 9acc60c3e2d449243e4c2126e3b56f1c4f7fd3bc ]

UART6 is used for debug (routed via uSD pins) and UART9 is connected
to the bluetooth chip.

Set indexed aliases to make the GENI UART driver happy and route serial
traffic through the debug uart by default.
