It seems that piece of hardware (gpio-connected orientation-sensors)
was really only used in the one s3c24xx-based device I hacked on in 2011.

I somehow lost focus from trying to do the s3c24xx devicetree migration
when I started hacking on Rockchip stuff, so while I do have the devices
still around, I don't think I'll find the time and energy trying to get a
recent kernel to run on them anyway, so I'm fine with dropping the driver.
It's simple enough to get reintroduced if someone really finds a device
using it or time to redo the ereader support using devicetree.

So long story short
