Bamboo P&T need to use second form of usb_set_report() to
ask to report tablet data.

With previous addition of Bamboo Touch, BTN_TOOL_TRIPLETAP is now used
for both TABLETPC2FG and BAMBOO_PT types.  So reduced check to
match type=TABLETPC2FG.

This change shows redundant check for !TABLETPC2FG in else statement.

Several devices use a high number of bits for scancodes. One important
group is the Remote Controllers. Some new protocols like RC-6 define a
scancode space of 64 bits.

The current EVIO[CS]GKEYCODE ioctls allow replace the scancode/keycode
translation tables, but it is limited to up to 32 bits for scancode.

Also, if userspace wants to clean the existing table, replacing it by
a new one, it needs to run a loop calling the ioctls over the entire
sparse scancode space.

To solve those problems, this patch extends the ioctls to allow drivers
handle scancodes up to 32 bytes long (the length could be extended in
the future should such need arise) and allow userspace to query and set
scancode to keycode mappings not only by scancode but also by index.

Compatibility code were also added to handle the old format of
EVIO[CS]GKEYCODE ioctls.

Folded fixes by:
- Dan Carpenter: locking fixes for the original implementation
- Jarod Wilson: fix crash when setting keycode and wiring up get/set
                handlers in original implementation.
- Dmitry Torokhov: rework to consolidate old and new scancode handling,
                   provide options to act either by index or scancode.

The Bamboo Touch reports a sub-screen resolution of 480x320.  The
signal-to-noise ratio is only about 100, so filtering is needed in
order to reduce the jitter to a usable level. However, the low
resolution leads to round-off errors in the EWMA filter, resulting in
extremely jerky pointer motion. This patch explicitly sets a higher
resolution for those devices, and tells this to the completion handler
via a low-resolution quirk.

The touch screen driver tries to find a range of free channels (which
are an array of bytes), by scanning for the "end of used channel" marker.
However it tries to be WAAAAY too smart and does 32 bit logic on 8 bit
quantities, and in the process completely gets it wrong
(repeatedly read the same register instead of incrementing in the loop,
assuming that if any of the 4 bytes in the 32 byte quantity is free,
all four are free, returning the channel number divided by 4 rather than
the actual first free channel number)

On the setting side, the same mistakes are made by and large; changed
this to just use the byte SCU write functions....

With these fixes we go from a completely non detected touchscreen to
something that appears to completely get detected.
