OpenRISC updates for 6.15

This is a bit late as I was on holiday, but as there are no huge structural changes I hope it's OK to include mid release cycle.

- Support for cacheinfo API to expose OpenRISC cache info via sysfs, this also translated to some cleanups to OpenRISC cache flush and invalidate API's
- Documentation updates for new mailing list and toolchain binaries
