kernel: 5.10: backport fix for lp55xx LED driver

This backports the upstream commit:
leds: lp55xx: Initialize enable GPIO direction to output

Without it under kernel 5.10 on Asus MAP-AC2200
the LED driver will fail probing:
[    1.947521] lp5523x: probe of 0-0032 failed with error -22

After the backported fix:
[    1.873236] lp5523x 0-0032: lp5523 Programmable led chip found
