Multiple changes squashed in single patch to avoid tick-tock effect and avoid breaking compilation/bisect 1. Per the hardware documentation, all changes to MCP_CONFIG, MCP_CONTROL, MCP_CMDCTRL and MCP_PHYCTRL need to be validated with a self-clearing write to MCP_CONFIG_UPDATE. Add a helper and do the update when the CONFIG is changed. 2. Move interrupt enable after interrupt handler registration 3. Add a new helper to start the hardware bus reset with maximum duration to make sure the Slave(s) correctly detect the reset pattern and to ensure electrical conflicts can be resolved. 4. flush command FIFOs Better error handling will be provided after interrupt disable is provided in follow-up patches.
