Subject: [PATCH] leds: bcm6328: fix signal source assignment for high leds

Each nibble represents 4 LEDs, and in case of the higher register, bit 0
represents LED 4, so we need to use modulus for the LED number as well.

Fixes: fd7b025a238d0a5440bfa26c585eb78097bf48dc ("leds: add BCM6328 LED driver")
