apphandler: Add firmware_revision support for ipmi config

Allow us to configure the firmware revision if needed. The field is
optional and will override the existing firmware revision.
This provide us a way to customize the firmware revision to anything we
want.

Tested:
With firmware_revision in dev_id.json
```
$ cat /usr/share/ipmi-providers/dev_id.json
$ ipmitool mc info
{
    "id": 0,
    "revision": 0,
    "addn_dev_support": 0,
    "firmware_revision": {
        "major": 35,
        "minor": 16
    },
    "manuf_id": 11129,
    "prod_id": 14426,
    "aux": 0
}
