Add AIM300 AIoT support along with usb, ufs, regulators, serial, PCIe,
and PMIC functions.
AIM300 Series is a highly optimized family of modules designed to
support AIoT applications. It integrates QCS8550 SoC, UFS and PMIC
chip etc.
Here is a diagram of AIM300 AIoT Carrie Board and SoM

This patch series depends on patch series:
"[PATCH v5 0/3] arm64: qcom-sm8[456]50: properly describe the PCIe Gen4x2 PHY AUX clock"
https://lore.kernel.org/linux-arm-msm/20240502-topic-sm8x50-upstream-pcie-1-phy-aux-clk-v5-0-10c650cfeade@linaro.org/
"[PATCH] arm64: dts: qcom: sm8550: Move some common usb node settings to SoC dtsi"
https://lore.kernel.org/linux-arm-msm/20240513084701.1658826-1-quic_tengfan@quicinc.com/

v7 -> v8:
  - rebase patch series on top of:
    https://lore.kernel.org/linux-arm-msm/20240502-topic-sm8x50-upstream-pcie-1-phy-aux-clk-v5-0-10c650cfeade@linaro.org/
  - add pinctrl configurations for pcie0 and pcie1 in AIM300 SOM dtsi
  - move some common usb node settings to SoC dtsi
  - verified with dtb check, and result is expected, because those
    warnings are not introduced by current patch series.
    arch/arm64/boot/dts/qcom/sm8550.dtsi:3037.27-3092.6: Warning
    (avoid_unnecessary_addr_size): /soc@0/display-subsystem@ae00000/dsi@ae96000: unnecessary
    #address-cells/#size-cells without "ranges" or child "reg" property
v6 -> v7:
  - correct typos in the commit message
  - move mdss_dsi0, mdss_dsi0_phy, pcie0_phy, pcie1_phy and usb_dp_qmpphy
    vdda supply to qcs8550-aim300.dtsi
  - move the perst and wake gpio settings of pcie0 and pcie1 to
    qcs8550-aim300.dtsi
  - move the clock frequency settings of pcie_1_phy_aux_clk, sleep_clk
    and xo_board to qcs8550-aim300.dtsi
  - verified with dtb check, and result is expected, because those
    warnings are not introduced by current patch series.

        from schema $id: http://devicetree.org/schemas/phy/qcom,sc8280xp-qmp-pcie-phy.yaml#

v5 -> v6:
  - move qcs8550 board info bebind sm8550 boards info in qcom.yaml

v4 -> v5:
  - "2023-2024" instead of "2023~2024" for License
  - update patch commit message to previous comments and with an updated
    board diagram
  - use qcs8550.dtsi instead of qcm8550.dtsi
  - remove the reserved memory regions which will be handled by
    bootloader
  - remove pm8550_flash, pm8550_pwm nodes, Type-C USB/DP function node,
    remoteproc_mpss function node, audio sound DTS node, new patch will
    be updated after respective team's end to end full verification
  - address comments to vph_pwr, move vph_pwr node and related
    references to qcs8550-aim300-aiot.dts
  - use "regulator-vph-pwr" instead of "vph_pwr_regulator"
  - add pcie0I AND pcie1 support together
  - the following patches were applied, so remove these patches from new
    patch series:
      - https://lore.kernel.org/linux-arm-msm/20240119100621.11788-3-quic_tengfan@quicinc.com
      - https://lore.kernel.org/linux-arm-msm/20240119100621.11788-4-quic_tengfan@quicinc.com
  - verified with dtb check, and result is expected, because those
    warnings are not introduced by current patch series.

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
