This adds support for my Thinkpad R52, which for some reason is not matched
by the "ThinkPad R52" line.

This reverts the mutex conversion that was recently done to the hdaps
driver; this coversion was buggy because the hdaps driver started using
this semaphore in IRQ context, which mutexes do not allow.  Easiest
solution for now is to just revert the patch (the patch was part of a
bigger GIT commit, 9a61bf63 but this
only reverts this one file)

convert drivers/hwmon/*.c semaphore use to mutexes.

the conversion was generated via scripts, and the result was validated
automatically via a script as well.

all affected hwmon drivers were build-tested.

Trivial patch to report both hdaps axises to the joystick device, not
just the X axis.

This allows us to eliminate the casts in the drivers, and eventually
remove the use of the device_driver function pointer methods for
platform device drivers.

In PM v1, all devices were called at SUSPEND_DISABLE level.  Then
all devices were called at SUSPEND_SAVE_STATE level, and finally
SUSPEND_POWER_DOWN level.  However, with PM v2, to maintain
compatibility for platform devices, I arranged for the PM v2
suspend/resume callbacks to call the old PM v1 suspend/resume
callbacks three times with each level in order so that existing
drivers continued to work.

Since this is obsolete infrastructure which is no longer necessary,
we can remove it.  Here's an (untested) patch to do exactly that.

- Remove the relative input device
- Add an absolute input device
- Misc. cleanup and bug fixing

The patch is sizable due to the cleanup from removing the relative input
device (net -112 lines).
