pieeprom-2023-11-20: 2712: Auto-detect support for PCIe expansion HAT (default + latest)

* Add autodetect support for PCIe expansion HATs
* Add PCIE_PROBE=1 to the EEPROM config for custom PCIe exapansion
  designs that do not support the upcoming HAT spec. This gives
  similar behaviour to CM4 where PCIe x1 is enumerated to discover NVMe
  devices.
* Fix loading of multiple initramfs images that are not 32-bit aligned sizes
  raspberrypi/firmware#1843
* Kernel load performance improvement - remove a memcpy
