Fix can mcp251xfd driver
The previous driver form a raspberry pi project for the Kernel 5.0 was broken. It was not safe to write and close the CAN socket in a short time interval.
Instead use the latest 5.10-rc1 implementation for the MCP51xFD driver. See also https://lwn.net/ml/linux-kernel/[email protected]/
Remove this patch if we want to rebase to a Linux kernel >= v5.10
