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.

There are two banks in 88pm8607. One is the normal bank, and the other
one is the test bank, it means it have the same register address in the
normal bank and test bank seperately.
For test bank register, it needs a special I2C sequence to acess as below,
    Touching to 0xFA address
    Touching to 0xFB address
    Touching to 0xFF address
    Accessing bank register
    Touching to 0xFE address
    Touching to 0xFC address
This sequence can't be interrupted. It means that we can't use
i2c_transfef() to implement touching 0xFA address. Otherwise, other i2c
operation may be inserted into 0xFA and 0xFB operation since the lock of
i2c_adapter is already released.
So for test bank we implemented specific i2c read/write operation;
