The ADP5585 family keypad decoder and IO expander is similar to the ADP5589,
however it features less IO pins, and lacks hardware assisted key-lock
functionality. Unfortunately the register addresses are different, as well as
the event codes and bit organization within the port related registers.
Move ADP5589 Register defines from the header file into the main source file.
Add new defines while making sure we don't break existing platform_data.
Add register address translation, and turn device specific defines into variables.
Introduce some helper functions and disable functions that doesn't
exist on the added devices.

The problem here is that max_effects can wrap on 32 bits systems.
We'd allocate a smaller amount of data than sizeof(struct ff_device).
The call to kcalloc() on the next line would fail but it would write
the NULL return outside of the memory we just allocated causing data
corruption.
The call path is that uinput_setup_device() get ->ff_effects_max from
the user and sets the value in the ->private_data struct. From there
it is:
-> uinput_ioctl_handler()
-> uinput_create_device()
-> input_ff_create(dev, udev->ff_effects_max);
I've also changed ff_effects_max so it's an unsigned int instead of
a signed int as a cleanup.

Apparently we never freed memory allocated when users open our char
devices nor removed old users from the list of connected clients.
Also unregister misc device immediately upon disconnecting the port
instead of waiting until last user drops off (refcounting in misc
device code will make sure needed pieces stay around while they
are needed) and make sure we are not holing holding serio_raw_mutex
when registering/unregistering misc device. This should fix potential
deadlock between serio_raw and misc device code uncovered by lockdep
and reported by Thomas Tuttle.

V2 hardware has many variants. This patch adddresses two issues:
- some model also has debounce packets, but with a different signature
than v3. Now we just check debounce for all v2 hardware.
- due to different scanning methods the hardware uses, x and y ranges have
to be calculated differently. And for some specific versions, we can just
see them as custom-made, so set {x, y} the same values as Windows driver
does.

shifted down 1 byte (where pressure was). This results in jumpy
1 finger touch and totally invalid 2nd finger data.
For touch detection, switch to a Touch Present single bit that
all versions of Bamboo support.
For touch 2 offset, calculate offset based on a bit that is set
different between the two packet layouts.
Since touch pressure reports were removed from driver, there was
no need to be reading pressure any more.
