mctp-controller-init: add i2c bus config

At the moment, the config for add i2c bug is done in
${machine}-mctp-i2c-bus-config.bb. It would be easier to ensure the i2c
bus be config here and make it fail to build if it's not.

Also, remove some configs don't take any effect.

Tested:
- building mctp-controller-init for my system without overriding:
```
| DEBUG: Executing shell function do_install
| Missing GBMC_MCTP_BUSES
```
- building mctp-controller-init for my system with go/gbmcl/156051:
```
cat tmp/work/*/mctp-controller-init/*/package/usr/share/mctp/i2c-bus-config.sh
bus="1 2 3 4 5 6 7 8 9"
```
