apldc/aplhidev: enable LEDs in xorg

[Tobias Heider]

This patch enables the capslock LED on apple m1/m2 laptops in xenocara.
Console mode was already working by setting the correct accessop, for
X we are missing an ioctl handler.

Only tested on apldc but the aplhidev code looks identical so the fix
should be the same.
