Title:
  [FFe] flash-kernel displays wrong "selected" DTB on various Pi models

Status in flash-kernel package in Ubuntu:
  Fix Released
Status in flash-kernel source package in Jammy:
  Fix Released

Bug description:
  [ Impact ]

  flash-kernel displays a "selected" DTB at the top of its output. On a
  Pi this isn't actually that relevant as it goes on to copy every DTB
  associated with the kernel anyway, but this is still confusing for
  users, especially when they see a completely different board model
  than the one they expected (e.g. at present on the Pi 400 or Pi 5, the
  output will indicate that the rpi-4-b dtb is being used).

  [ Test Plan ]

  * Boot a jammy image on an affected model of Pi (400, 5, CM3, CM3+, Zero 2W)
  * Run "sudo flash-kernel" and confirm it outputs "Using DTB: bcm2711-rpi-4-b.dtb" at the top of its messages
  * Enable the -proposed pocket and "sudo apt update"
  * "sudo apt install flash-kernel" to update flash-kernel to the proposed version
  * Run "sudo flash-kernel" and confirm it outputs the correct DTB for the selected model of Pi.

  [ Regression Potential ]

  Low; the existing flash-kernel already copies all DTBs found and the
  proposed one will too (all Pi related entries use "Method: pi", the
  method isn't changing in its behaviour, the only db entries that are
  changing are Pi related). Thus the worst-case scenario is that flash-
  kernel continues to output the "wrong" DTB at the top of its output,
  which is no worse than the present situation.

  [ Original Description ]
  flash-kernel probably shouldn't even be dealing with the DTBs on Pi but it's picking the wrong one for some machine models. For example on a Raspberry Pi 400 Rev 1.0 it uses bcm2711-rpi-4-b.dtb. Same one Compute Module 3 and 3+.

  It's probably because in /usr/share/flash-kernel/db/all.db the catch-
  all

  Machine: Raspberry Pi *

  is listed before these above mentioned models (and others as well).
