[PATCH v6] platform/x86: Add wmi driver for Casper Excalibur laptops

[Mustafa Ekşi]

Hi, I apologize for the delay. I recently saw Carlos's patch and your
reviews, so I improved my driver according to it and made it ready for
another version.

I didn't include the documentation for the new zoned keyboard backlight
naming since Carlos is going to do that. However, I changed the naming of
corner led because it isn't affected when other zones' brightness changes.
And one last reason to not name it kbd_zoned_backlight is the fact that it
isn't on the keyboard, it's on the two corners of the laptop. I'm still not
sure how to name it, so I named it 'backlight'.
Here's a photo of the laptop: https://imgur.com/a/JEqMiGL
