Update existing documentation for qcom,msm-id (interchangeably: qcom,soc-id) and qcom,board-id. Add support for qcom,pmic-id, qcom,oem-id to support multi-DTB selection on Qualcomm's boards. "qcom,soc-id", "qcom,board-id" and "qcom,pmic-id" are tuples of two 32-bit values. The "qcom,oem-id" is a tuple of one 32-bit value. Introduce macros to help generate SOC, board, PMIC and OEM identifiers. QCOM_SOC_ID and QCOM_SOC_REVISION can be used to generate qcom,msm-id. QCOM_BOARD_ID and QCOM_BOARD_SUBTYPE can be used to generate qcom,board-id. QCOM_PMIC_SID and QCOM_PMIC_MODEL can be used to generate qcom,pmic-id. QCOM_OEM_ID can be used to generate qcom,oem-id. Add entries for different types of SoC, boards, DDR type, Boot device type which are currently used by Qualcomm based bootloader.
