pieeprom-2025-01-06: 2712: Stop the fan after fan-probe (latest)

Browse Source 
* Stop the fan after after fan-probe
  After the fan-probe has completed drive the fan PWM GPIO
  to high if a fan was detected and let the OS take over.
* Add SD_QUIRKS for hardware bringup / workarounds
  Add a new SD_QUIRKS flags property which can be used to
  disable high-speed mode (bit 0). Other bits are reserved for
  future use.
* Change uart_2ndstage default to 1 on Pi5
  Change the default to 1 because this gives useful diagnostics
  for device-tree loading with minimal overhead. Set uart_2ndstage=0
  or BOOT_UART=0 to disable this.
* Move M.2 HAT+ detection to early boot.
  Initialse M.2 HAT+ detection before DDR init to give NVMe
  drive firmware more time to boot.
