[PATCH RFC] leds: Allow heartbeat trigger to use user-defined brightness.

[ygeorgie <ygeorgie@gmail.com>]

From: Yury Georgievskiy <ygeorgie@gmail.com>

Led brightness for PWM leds can be dynamically adjusted.
GPIO leds are not affected as only on/off states are possible.

Checked with PWM leds.
Writing new value in /sys/class/leds/led-pwm::/brightness
alter PWM led brightness as expected.
