All hardware >= GTA01Bv4 has the capability of doing PWM on the vibrator.

However, the kernel driver for this was never implemented.

The bad news is that there just is no standard interface on how to control a
non-backlight pwm from userspace, so we have to invent our own interface, again.

However, that driver should be generic enough to cover all the s3c24xx PWM's
that we use, i.e. also for LED brightness control on GTA02.
