Change SPI pins about canhack

[kentindell]

The CAN drivers are in another repository: https://github.com/kentindell/canis-can-sdk

The SPI pins are set in the header file: https://github.com/kentindell/canis-can-sdk/blob/main/mcp25xxfd/rp2/mcp25xxfd-rp2.h

You can modify this file to add extra board support. If you want, you can create some macro fu that when allows arbitrary board definition headers to be pulled in, then I will accept a pull request for this so that you don't need to maintain a fork of the repo.

Thanks for the info. I am not very familiar with working with C Macros and change is very simple so I don't think I can submit such patch. Just wondering is the SPI_IRQ macro corresponds to ~INT (pin 19 of SSOP)? The MCP251863 also has ~INT0 and ~INT1 are they used in the driver?
