[Bug 1867071] [NEW] Raspberry Pi uses old, non-upstream DTB naming (bcm2710 instead of bcm283*)

[Qwerty Chouskie]

Public bug reported:

The upstream Debian package is correct, but the Ubuntu version of the
package, even in Focal, uses the old bcm2710-* naming, which is a
holdover from the days before upstream RPi support was put merged into
mainline Linux.  This causes errors when using U-Boot as a uEFI
implementation and the stock arm64 Ubuntu image with the stock arm64
Ubuntu kernel, as every kernel upgrade, flash-kernel is looking for the
wrong file name.  (Side note, the RPi 4 does use bcm2711-rpi-4-b.dtb in
the upstream kernel, but every other Pi is using bcm2835 - bcm2837).

** Affects: flash-kernel (Ubuntu)
     Importance: Undecided
         Status: New
