The difference is that the interface is platform-specific, contrary to
the SPI and I2C interfaces which are platform-neutral.
Platform-specific drivers are supposed to go to drivers/platform, or at
least this is my understanding. Plus, hp_accel isn't only an interface
to the accelerometer chip, it also links with a led. Having hp_accel
next to hdaps does make sense, don't you think?

That being said, I don't have a strong opinion on this, and it will
have to be revisited the day all accelerometer drivers gain a dedicated
home anyway. If anyone disagree with my decision and has a motivated
suggestion for something better, please speak up.
