Change SPI pins

[acedogblast]

Hello I have a custom rp2040 based board using MCP251863. I was able to build Micro-python along with the added CAN related code from this repo (except the MIN_PROTOCOL support due to a build error). I have not been able to find out where the GP# pins are defined to interface with the MCP251863. On my board it uses GP pins 8 through 11 which is part of the second SPI bus of the rp2040. Where can I set the SPI pins? Thank you.
