This includes overlays for individual can devices
but also support for the quadcan-fd hat

can: mcp25xxfd: optimize reception of big CanFD frame reception with BRS

In case of predicted DLC=15 and in case at least 33% of those are
sent via BRS be aggressive and use bulk fifo reads to avoid missing
any frames due to releasing FIFOs not as fast as possible.

This would be of most impact when having a 1MHz Can Bus with
a 8MHz data bitrate.

can: mcp25xxfd: fix rx can-fd reception

dlc instead of length was passed as argument - fixed

can: mcp25xxfd: setup tdc more reliably and allow configuration

Missing CAN framework support for control/configuration of tdc
via netlink so for now these are module parameters.
