Try to be less smart (focused on the one target/one use-case),
instead reduce the rpi-firmware package to a selectable list
of (verbatim) installed firmware files.
- change rpi-firmware config handling from rpi-variant/rpi-flavour
choices to bootcode.bin, pi-default/-extended/-cut-down and
pi4-/default/-extended/-cut-down selection
- add BR2_PACKAGE_RPI_FIRMWARE_CONFIG_FILE option to select installable
config.txt file
- remove config.txt modify code/handling from raspberry post-image.sh
script
- add different customized config.txt files to the raspberry board
section
- change dtoverlay krnbt from 'dtoverlay=miniuart-bt,krnbt=on' to extra line
with explanation comment
- change raspberry defconfigs to select appropiate rpi-firmware
and config.txt files
- change genimage-raspberrypi4.cfg/genimage-raspberrypi4-64.cfg to
use start4.elf and fixup4.dat
- update board/raspberrypi/readme.txt (add optional files fixup4.dat,
start4.elf and zImage)
With this changes a better support for custom use-cases should
be possible, specially multi-target SD cards as suggested by
Stefan Agner ([1]).

[yann.morin.1998@free.fr: fix case of no config.txt provided]

Since commit 'package/rpi-firmware: fix startup file names' ([1]) the
start and fixup file names are normalized to start.elf/fixup.dat,
adjust the rpi4 genimage config files accordingly.
Fixes:
ERROR: file(rpi-firmware/fixup4.dat): stat(.../images/rpi-firmware/fixup4.dat) failed: No such file or directory
ERROR: vfat(boot.vfat): could not setup rpi-firmware/fixup4.dat
