interrupt pin connected.

STMPE801 is a GPIO expander. Registers for 801 are much different from other
variants. This patch adds support for STMPE801 in stmpe mfd driver.

STMPE610 is very much like STMPE811, except the number of gpio pins, which is 8
in 811 and 6 in 610. This patch adds support for variant 610. STMPE610 will
share most of the code with STMPE811.

Few STMPE controller can have register interface over SPI or I2C. Current
implementation only supports I2C and all code is present in a single file
stmpe.c. It would be better to separate out I2C interface specific code from
controller specific code. Later SPI specific code can be added in a separate
file.

This patch separates out I2C and controller specific code into separate files,
making stmpe.c independent of I2C.

On many boards, stmpe is present as an separate device (not as part of SoC).
Here gpio lines are mostly used for getting interrupts. This patch adds in
support to handle irq over gpio pin.

Generating kerneldoc for STMPE result in warnings, so fix this by
adding missing documentation.

The genirq core is being updated to supply struct irq_data to irq_chip
operations rather than an irq number. Update the SMTPE driver to the new
APIs.
