leds: tps6131x: Increase overvoltage protection threshold to 6V

Browse Source 
Currently, there may be cases where the overvoltage detection is triggered
even with a valid and generally functioning hardware setup. This occurs,
for example, when the input voltage exceeds the currently used overvoltage
threshold of 4.65V (typical). Since input voltages up to 5V are supported,
the threshold should be adjusted accordingly.

While the target output voltage setting has no effect on the LED operation
used here, it indirectly selects the threshold for overvoltage detection.
Set this to a value of 4.95V to select a threshold of 6V (typical).
