* As of now the code account only max_brightness > 255
-> Check if max_brightness != 255 and apply the scaling
even if the max_brightness is less then 255

* Use O_WRONLY for write
* Return errno for write
* Log all failures
* Fix read_int():
We would always treat strtol(...) = 0 as an error,
although the real value can very well be 0.
Check the end pointer to fix this.

The old exynos4x12 lights HAL had logic for scaling the brightness of
lights according to the light's type and also scaling each R/G/B colour.
Bring this logic across, and make the battery LED not eye-searing at
night.
Based on work by Daniel Hillenbrand.
