dt-bindings: PCI: qcom: Convert to YAML

Changes to the schema:
 - Fixed the ordering of clock-names/reset-names according to
   the dtsi files.
 - Mark vdda-supply as required only for apq/ipq8064 (as it was marked
   as generally required in the txt file).

Changes to examples:
 - Inline clock and reset numbers rather than including dt-bindings
   files because of conflicts between the headers
 - Split ranges and reg properties to follow current practice
 - Change -gpio to -gpios
 - Update IRQ flags to LEVEL_HIGH rater than NONE
 - Removed extra "snps,dw-pcie" compatibility.

Note: while it was not clearly described in text schema, the majority of
Qualcomm platforms follow the snps,dw-pcie schema and use two
compatibility strings in the DT files: platform-specific one and a
fallback to the generic snps,dw-pcie one. However the platform itself is
not compatible with the snps,dw-pcie interface, so we are going to
remove it.
