pieeprom-2025-06-09: 2712: NVMe: Fix loading of files > 32MB (latest)

Browse Source 
* NVMe: Fix loading of files > 32MB
  Fix an NVMe boot bug which caused large contiguous reads >= 32MB to fail
* Update setting alpha for 2712D0
  D0 moved the alpha blend mode from CTL2 to CTL0.
  Update the bootloader code to follow suit for those using
  the simple framebuffer
* dtoverlay: Fix node_is_enabled for implicit status
  The absence of a status property implies that a node is enabled. Update
  dtoverlay_node_is_enabled to match that behaviour.
  See: https://github.com/raspberrypi/firmware/issues/1970
* arm_loader: GET_CLOCKS: Set useful response length
  The kernel's firmware mailbox API does not make the actual length of the
  response available to clients, but other implementations may care.
  Continue to pad the GET_CLOCKS buffer with zeroes, but set the response
  length to minimally contain the useful content.
