Qualcomm UART (Data Mover mode)

Required properties:
- compatible: must be "qcom,msm-uartdm-v1.4"
- reg: start address and size of the registers
- clock: interface clock (must accept baudrate as a frequency)

Optional properties:
- bit-rate: Data Mover bit rate register value
			(If not defined then 0xCC is used as default)
serial: Add support for Qualcomm serial port This driver works in "new" Data Mover UART mode, so will be compatible with modern Qualcomm chips only.

msm_serial: Read bit rate register value from DT IPQ40xx and currently supported Snapdragon boards don't use the same one so enable reading it from DT, if no DT property is found default value is the same as the previous define.
