[PATCH 0/8] STMPE fixes/rework and add STMPE1600 support

[<patrice.chotard@xxxxxx>]

From: Patrice Chotard <patrice.chotard@xxxxxx>

This series cleans and fixes some bugs in MFD/GPIO STMPE drivers and prepare
 the ground to add new STMPE1600 support.

STMPE1600 datasheet is available here : 
http://www2.st.com/content/st_com/en/products/interfaces-and-transceivers/
i-o-expanders-and-level-translators/i-o-expanders/stmpe1600.html

Only STMPE1600 has been tested on STM32 platform. As i have no board with
others STMPE variant(STMPE610/STMPE801/STMPE811/STMPE1601/STMPE1801/STMPE2401
and STMPE2403), i put in CC boards's maintainers which are using others STMPE variant.

If they can kindly check that no regression has been introduce by this series
