Input: stmfts - fix setting ABS_MT_POSITION_* maximum size

Browse Source 
The commit 78bcac7b2a ("Input: add support for the STMicroelectronics
FingerTip touchscreen) used the 'touchscreen_parse_properties()' helper
function in order to get the value of common properties.

But, commit 78bcac7b2a didn't set the capability of ABS_MT_POSITION_*
before calling touchscreen_parse_properties(). In result, the max_x and
max_y of 'struct touchscreen_properties' were not set.
