Gaël PORTAY 250a3544bf board/raspberrypi: reword console comment
The Raspberry Pi with Bluetooth connectivity up to 4 (i.e. Zero W, Zero
2 W, 3, 4 and Compute Module 4) use the miniuart-bt overlay to restore
UART0 for the serial console (like the Raspberry Pi and Raspberry Pi 2
that have no Bluetooth); the Bluetooth uses the mini-UART instead[1][2].

This rewords the comment instead of enumerating every hardwares that can
be extended in the future.
