The phyBOARD-Lyra has a GPIO fan header. This overlay enables the fan
header and sets the fan to turn on at 65C.

v2:
- Change overlay name from k3-am62-... to k3-am62x-...
- Add compile time test

There is no need to set the status. If no status is present, it also
indicates that the node is activated.
