OpenBMC v1.99.6

I just release v1.99.6 which has 86 commits since v1.99.5. Half of these commits were version increases to underlying OpenBMC repositories with new features and bug fixes.

Highlights are as follows:

- Fan control
- Beginning of a reference fan control using phosphor-hwmon which sets fans to high speed on boot of managed host
- Code update
- More work in prep for UBI-managed PNOR
- systemd targets to block boots while code update is in progress
- State management
- Soft poweroff requests to the Host on shutdown
- Refactored transition targets for consistency
- Bug fixes for BMC reboot while host is running
- Error management
- Assert fault LED groups when an error indicates a failing part
- Better support for repository-local errors
- LEDs
- Add "lamp test" mode, typically used in system manufacturing.
- OpenPOWER
- OCC AMESTER passthru fixes
- Virtual PNOR daemon now provides mboxctl to control flushing PNOR cache. 45 second sleep in boot paths now removed.
- Machine specific
- Quanta Q71L - Add configuration for phosphor-hwmon
