Change all call sites in drivers/input to not access the ABS axis
information directly anymore. Make them use the access helpers instead.
Also use input_set_abs_params() when possible.

For more clearance what the functions actually do,
usb_buffer_alloc() is renamed to usb_alloc_coherent()
usb_buffer_free() is renamed to usb_free_coherent()
They should only be used in code which really needs DMA coherency.
All call sites have been changed accordingly, except for staging
drivers.

The device does not emit EV_MSC/MSC_SERIAL nor EV_KEY/BTN_MIDDLE events
so it should not mark them as supported in capabilities bitmaps. This
still leaves BTN_TOOL_PEN and BTN_TOUCH events being processed in a funky
manner.

When Wacom devices wake up from a sleep, the switch mode command
(wacom_query_tablet_data) is needed before wacom_open is called.
wacom_query_tablet_data should not be executed inside wacom_open
since wacom_open is called more than once during probe.
wacom_retrieve_hid_descriptor is removed from wacom_resume due

Touch enbaled devices share the same product ID with pen. However,
we do not want to post touch events while pen is in prox. To do so,
we used to keep a local static variable to keep track of if pen is
in prox or not. This works fine for Tablet PC devices since there
is only one device attached. With the newer touch enabled regular
tablets, we can not make this assumption any more, i.e, one system
may have more than one identical tablet plugged in.
This patch adds an new entry, shared, into the struct wacom_wac so
touch data can access pen data to locally. This solution assumes
the two tools (touch and pen) of the same ID will be probed one
after the other without interruption in between by another Wacom
device of the same ID.
Process out and in prox events for Graphire and Tablet PC devices
in the same loop to simplify the data parsing logic.
[re-applying after revert since other patches are based on this one]
