545e88cb41 dt-bindings: PCI: qcom: Do not require 'msi-map-mask'
Whether the 'msi-map-mask' property is needed or not depends on how the
MSI interrupts are mapped and it should therefore not be described as
required.

Note that the current schema fails to detect omissions of the mask
property if the internal MSI controller properties are also present.

c8073025c0 dt-bindings: PCI: qcom: Allow 'required-opps'
Some Qualcomm SoCs require a minimum performance level for the power
domain so add 'required-opps' to the binding.

b8d3404058 dt-bindings: PCI: qcom,pcie-sm8550: Move SM8550 to dedicated schema
The qcom,pcie.yaml binding file containing all possible Qualcomm SoC
PCIe root complexes gets quite complicated with numerous if:then:
conditions customizing clocks, interrupts, regs and resets.  Adding and
reviewing new devices is difficult, so simplify it by having shared
common binding and file with only one group of compatible devices:

1. Copy all common qcom,pcie.yaml properties (so everything except
   supplies) to a new shared qcom,pcie-common.yaml schema.
2. Move SM8550 PCIe compatible devices to dedicated binding file.

This creates equivalent SM8550 schema file, except:
 - Missing required compatible which is actually redundant.
 - Expecting eight MSI interrupts, instead of only one, which was
   incomplete hardware description.
