[RESEND,0/6] Add Microchip MCP25XXFD CAN driver

Hello,

This series adds CAN network driver support for Microchip MCP25XXFD CAN
Controller with MCP2517FD as the target controller version. This series is
mostly inspired (or taken) from the previous iterations posted by Martin Sperl.
I've trimmed down the parts which are not necessary for the initial version
to ease review. Still the series is relatively huge but I hope to get some
reviews (post -rcX ofc!).

Link to the origial series posted by Martin:
https://www.spinics.net/lists/devicetree/msg284462.html

I've not changed the functionality much but done some considerable amount of
cleanups. This series has been tested on 96Boards RB3 platform by myself and
Martin has tested the previous version on Rpi3 with external MCP2517FD
controller.

Thanks,
Mani
