Subject: [PATCH v1 0/5] Add STM32MP25 PCIe drivers

This patch series adds PCIe drivers STM32MP25 SoC from STMicrolectronics
and respective yaml schema for the root complex and device modes.

Changes in v1:
   Address comments from Rob Herring and Bjorn Helgaas:
   - Drop st,limit-mrrs and st,max-payload-size from this patchset
   - Remove single reset and clocks binding names and misc yaml cleanups
   - Split RC/EP common bindings to a separate schema file
   - Use correct PCIE_T_PERST_CLK_US and PCIE_T_RRS_READY_MS defines
   - Use .remove instead of .remove_new
   - Fix bar reset sequence in EP driver
   - Use cleanup blocks for error handling
   - Cosmetic fixes
