arm: dts: msm: add GENI SE QUP device tree node
On modern Qualcomm platforms including SDM845 a GENI SE QUP IP
description is supposed to be found in board device tree nodes,
the version of the IP is used by the GENI UART driver to properly
set an oversampling divider value, which impacts UART baudrate.
The change touches dragonboard845c and starqltechn board device
tree source files, a device tree node label to "debug" UART is
renamed to 'uart9' according to the naming found in Linux.
