Input: atmel_mxt_ts - use snprintf for sysfs attribute show method
Sysfs attribute show methods are always passed a buffer of length
PAGE_SIZE. To keep from overwriting this buffer and causing havoc, use
snprintf() to guarantee we never write more than the buffer can hold.
In addition, at least for my touchscreen, the number and size of objects
was far too big to fit in a single 4K page. Therefore, this patch also
trims some redundant framing text to leave more room for actual data.

Input: atmel_mxt_ts - report pressure information from the driver
Atmel mxt1386 touch controller has the touch pressure information so
let's report it to the user space.
[dtor@mail.ru: added ABS_RESSURE reporting for ST emulation.]

Input: atmel_mxt_ts - remove matrix size check
The mxt_check_matrix_size() is currently setting the CTE mode to match
xline/yline information that is in the platform data, but it does not
take into account for example the fact that we could have a key array
in use too (key array would use some x/y lines as well).
It would be better to simply rely on the configuration data, and make
sure that the CTE mode set in there matches the touch object (touchscreen,
key array, proximity) configuration (which are set in the config data too).
