Subject: [PATCH 097/182] ARM: debug: qcom: make UART address selection
configuration option
Separate Qualcomm low-level debugging UART to two options.
DEBUG_MSM_UART is used in earlier non-multi platform arches,
like MSM7X00A, QSD8X50 and MSM7X30.
DEBUG_QCOM_UARTDM is used in multi-plafrom arches and have
embedded data mover.
Make DEBUG_UART_PHYS and DEBUG_UART_BASE user adjustable by
Kconfig menu.
