leds: lm3692x: Make sure we don't exceed the maximum LED current
The current is given by the formular from page 12 of
https://www.ti.com/lit/ds/symlink/lm36922.pdf. We use this to limit the
led's max_brightness using the led-max-microamp DT property.
The formula for the lm36923 is identical according to the data sheet.
