- Convert all the bit shifting flag in leds.h to use the BIT macro.
- Removed inline modifiers for the timer helper function.

This patch adds a hrtimer to ledtrig-transient so that when driver is
registered with LED_BRIGHTNESS_FAST, the hrtimer is used for the better
time accuracy in handling the duration.
