* 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
