feat(msm8916): allow selecting which UART to use

At the moment the msm8916 platform port always uses UART number 2 for
debug output. In some situations it is necessary to change this, either
because only the other UART is exposed on the board or for runtime
debugging, to avoid conflicting with the normal world.

Make the UART to use configurable using QTI_UART_NUM on the make
command line and also add QTI_RUNTIME_UART as an option to keep using
the UART after early boot. The latter is disabled by default since it
requires reserving the UART and related clocks inside the normal world.
