Subject: Store backlight breathing state in EEPROM (#6105)

* Store backlight breathing state in EEPROM

* Reduce backlight_config.level from 6 bits to 4 (max 15 "on" levels)

* Error out if BACKLIGHT_LEVELS is > 15

* Remove mention of default backlight pin in rules.mk template

* Remove pointless comment
