rpi4: remove bootcode.bin
Browse files Browse the repository at this point in the history
While the existence of bootcode.bin is not harmful, according
to the Raspberry Pi documentation:
https://www.raspberrypi.com/documentation/computers/configuration.html#bootcode-bin

it is not necessary for the Raspberry Pi 4B to contain this
firmware.
