Boris Gjenero 4b85c93cd8 Improve rockbox_flash messages
- For V2 and FM Recorders, don't recommend bootloader upgrade
  due to FS#12426 BootBox bugs.
- When rockbox.ucl can't fit and the bootloader is old, the
  bootloader needs to be upgraded.
- When RomBox start address differs, the bootloader is
  not compatible with RomBox.
