The hp_accel driver isn't a hardware monitoring driver, so it doesn't
belong to drivers/hwmon. Move it to drivers/platform/x86, assuming HP
doesn't ship non-x86 laptops.

Changes since v1:
* Update hp_accel driver path in Documentation/hwmon/lis3lv02d.
* Move hpfall.c to Documentation/laptops.
Not tested due to lack of hardware.
