pru: BeagleBone Firmware upgrade to Debian 11.7 Bullseye (#6577)

* Porting BeagleBone to Kernel 5.10

* Fixing issue with installation for BeagleBone.

This fix resolve 2 issue:
1. Conflict with AVR packages.
2. "klipper_pru" script is executed before PRU cores are ready

* Adding additional steps to BeagleBone install guide.

* Updating BeagleBone documentation, adding different use cases, adding buses configurations SPI, I2C, CAN, UART
