Now that we have a proper API to set the attention data, there is
no point in keeping it in the transport driver.

If struct rmi_device_platform_data contains pointers to other struct,
it gets difficult to allocate a fixed size struct and copy it over between
drivers.
Change the pointers into a struct and change the code in rmi4 accordingly.

Commit 5b65c2a029 ("HID: rmi: check sanity of the incoming report") added
support for handling incomplete HID reports do to the input data being
corrupted in transit. This patch reimplements this functionality in the
function drivers so they can handle getting less valid data then they
expect.

According to the RMI4 spec the maximum size of F12 control register 8 is
15 bytes. The current code incorrectly reports an error if control 8 is
greater then 14. Making sensors with a control register 8 with 15 bytes
unusable.

The pointer to struct rmi_function in f12_data is never set and was never
used. The fn pointer is also stored in rmi_2d_sensor which is a member of
f12_data.
