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.

The 'switch' sysfs attribute is used for
showing and setting the switch state of the device.
However, setting it from the userspace focibly is not appropriate.
And showing the state can be handled from
other places (e.g. external connector) in a unified manner.
This patch removes the sysfs attribute.
Plus, uevent messages for interrupts are also removed.
