package: add support for LEDS_SYSCON per board

Currently there is no package enablement for LEDS_SYSCON, which means that
for boards that map certain LEDs through syscon registers (like the
Realtek Hasivo switch series, mapping LEDs through STC8 MFD driver), the
LEDS_SYSCON would otherwise need to be enabled at a full target level.

This package will allow individual boards to bring in syscon LED support.
