Fix RG Sleep issues for Teensy Controllers

Appearenly, teensy controllers have some issues with waking up.  If the rgblight is called "too soon", it will cause the controller to lock up, intermittently. Adding a 10 ms
delay seems to fix this issue, as it lets it have enough time to handle things properly.

This has been tested extensively on my Ergodox EZ, and can be seen in the @drashna userspace, under the "suspend_wakeup_init_user" function.
