Input: wacom - prepare for syncing with input-mt changes

Henrik added new MT routines in release 3.7. This patch is to prepare
for the use of new MT routines.

In the newly added wacom_abs_set_axis() function, the first
if-statement assigns ABS_X/Y for number of contacts less or equal
to 2. So, it is single and 2 finger touch devices. Two finger touch
devices are processed here since they will not use the updated
input_mt_init_slots(), which does not offer benefit to those devices.

input_mt_init_slots() will take care of ABS_X/Y assignment when flags
are not zero. All touch devices with more than two contacts will use
input_mt_init_slots() with non-zero flags.

The second if-statement is for all MT devices, which include two
finger touch devices.

Input: sysrq - allow specifying alternate reset sequence

This patch adds keyreset functionality to the sysrq driver. It allows
certain button/key combinations to be used in order to trigger emergency
reboots.

Redefining the '__weak platform_sysrq_reset_seq' variable is required
to trigger the feature.  Alternatively keys can be passed to the driver
via a module parameter.

This functionality comes from the keyreset driver submitted by
Arve Hjønnevåg in the Android kernel.
