drivers/video/backlight/aat2870_bl.c: fix setting max_current
- Current implementation tests wrong value for setting aat2870_bl->max_current. - In the current implementation, we cannot differentiate between 2 cases: a) if pdata->max_current is not set , or b) pdata->max_current is set to AAT2870_CURRENT_0_45 (which is also 0). Fix it by setting AAT2870_CURRENT_0_45 to be 1 and adjust the equation in aat2870_brightness() accordingly.
