Added power tracking api (#12691)
* Add power tracking API to lufa and chibios targets * power.c: Pass through power state to the notify function * power: added notify_power_state_change_user too. * making it pass the PR linter * Add a POWER_STATE_NO_INIT state, that we start in before calling power_init(); * Rename *power* to *usb_power* * removing stray newline * Rename usb_power* to usb_device_state* * Update quantum/usb_device_state.h Co-authored-by: Drashna Jaelre <drashna@live.com> * Fix comment * usb_device_state.h: Don't include quantum.h, only the necessary headers. Co-authored-by: Drashna Jaelre <drashna@live.com>
