meta-ampere: Support UID button and LED

The UID button is used to provide visual identification of the system
when pushed. Pressing the UID button toggles the UID LED. The same
action can be done via Redfish (by patching IndicatorLED from
redfish/v1/Systems/system) or the IPMI chassis identify command.

Tested:
1. Press the UID button to toggles the UID on/off
2. Turn on the UID LED via ipmi command
      $ ipmitool chassis identify
3. Turn Lit/Blinking/Off UID LED via Redfish then check the IndicatorLED
   values
$ curl -X PATCH --user root:0penBmc -H "Content-Type: application/json" \
     -H "If-Match: *" --insecure https://BMC_IP/redfish/v1/Systems/system \
     -d '{"IndicatorLED": "Lit/Blinking/Off"}'
$curl -X GET --user root:0penBmc -H "Content-Type: application/json" \
      --insecure https://BMC_IP/redfish/v1/Systems/system
      The IndicatorLED is "Lit/Blinking/Off"
