This series adds support for Amazon's Annapurna Labs DT-based PCIe host
controller driver.
Additionally, it adds 3 quirks (ACS, VPD and MSI-X) and 2 generic DWC patches.

Changes since v3:
- Removed PATCH 8/8 since the usage of the PCI flags will be discussed
  in the upcoming LPC
- Align commit subject with the folder convention
- Added explanation regarding ECAM "overload" mechanism
- Switched to read/write{_relaxed} APIs
- Modified a dev_err to dev_dbg
- Removed unnecessary variable
- Removed driver details from dt-binding description
- Changed to SoC specific compatibles
- Fixed typo in a commit message
- Added comment regarding MSI in the MSI-X quirk

Changes since v2:
- Added al_pcie_controller_readl/writel() wrappers
- Reorganized local vars in several functions according to reverse
  tree structure
- Removed unnecessary check of ret value
- Changed return type of al_pcie_config_prepare() from int to void
- Removed check if link is up from probe() [done internally in
  dw_pcie_rd/wr_conf()]

Changes since v1:
- Added comment regarding 0x0031 being used as a dev_id for non root-port devices as well
- Fixed different message/comment/print wordings
- Added panic stacktrace to commit message of MSI-x quirk patch
- Changed to pci_warn() instead of dev_warn()
- Added unit_address after node_name in dt-binding
- Updated Kconfig help description
- Used GENMASK and FIELD_PREP/GET where appropriate
- Removed leftover field from struct al_pcie and moved all ptrs to
  the beginning
- Re-wrapped function definitions and invocations to use fewer lines
- Change %p to %px in dbg prints in rd/wr_conf() functions
- Removed validation that the port is configured to RC mode (as this is
  added generically in PATCH 7/8)
- Removed unnecessary variable initializations
- Swtiched to %pR for printing resources
