Bamboo One's with ID of 0x6a and 0x6b were added with correct
indication of 1024 pressure levels but the Graphire packet routine
was only looking at 9 bits.  Increased to 10 bits.

This bug caused these devices to roll over to zero pressure at half
way mark.

The other devices using this routine only support 256 or 512 range
and look to fix unused bits at zero.

Do not register battery device until connected to a tablet.
This prevents an empty battery icon from being shown when tablet is
connected using USB cable.

Also, call power_supply_powers() for apps that can make use of that
info.

And stop ignoring input registration failures.

Main part of patch is adding support for a new Wacom MT touch
packet and labels these devices using MTSCREEN type.

Other items of interest:

Delete some duplicate code in HID parsing for Y info since
its already done in X path.

In wacom_query_tablet_data(), only invoke the set report
that requests tablets to send Wacom Touch packets for
Finger interfaces.  Mostly, this is to make code intent clear.
