Subject: [PATCH v4 0/6] arm64: qcom: add AIM300 AIoT board support

Add AIM300 AIoT support along with usb, ufs, regulators, serial, PCIe,
sound card and PMIC functions.
AIM300 Series is a highly optimized family of modules designed to
support AIoT applications. The module is mounted onto Qualcomm AIoT
carrier board to support verification, evaluation and development. It
integrates QCS8550 SoC, UFS and PMIC chip etc.

v3 -> v4:
  - use qcm8550.dtsi instead of qcs8550.dtsi, qcs8550 is a QCS version
    of qcm8550, another board with qcm8550 will be added later
  - add AIM300 AIoT board string in qcom.yaml file
  - add sm8550 and qcm8550 fallback compatible
  - add qcm8550 SoC id
  - add reserved memory map codes in qcm8550.dtsi
  - pm8010 and pmr73d are splited into carrier board DTS file. Because
    the regulators which in pm8550, pm8550ve and pm8550vs are present
    on the SoM. The regulators which in pm8010 and pmr73d are present
    on the carrier board.
  - stay VPH_PWR at qcs8550-aim300.dtsi file

      VPH_PWR is obtained by vonverting 12v voltage into 3.7 voltage
      with a 3.7v buck. VPH_PWR is power supply for regulators in AIM300
      SOM. VPH_PWR regulator is defined in AIM300 SOM dtsi file.

v2 -> v3:
  - introduce qcs8550.dtsi
  - separate fix dtc W=1 warning patch to another patch series

v1 -> v2:
  - merge the splited dts patches into one patch
  - update dts file name from qcom8550-aim300.dts to qcs8550-aim300 dts
  - drop PCIe1 dts node due to it is not enabled
  - update display node name for drop sde characters
