mfd: aat2870: No need to check return value of debugfs_create functions

When calling debugfs functions, there is no need to ever check the
return value. The function can work or not, but the code logic should
never do something different based on this.

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.
