sm6150-common: camera: Cap max_brightness

Browse Source 
* Our maximum brightness is 500.
* However, for safety related reason, I have capped this to 255.
* 255 is more than sufficient, and I do not want to be responsible for LED damage.

* Finding the default percentage took some trial and error, in this case, 59% correlated to 75.
