[PATCH 03/11] Input: synaptics-rmi4 - have only one struct platform data

[Benjamin Tissoires]

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.

this patch will conflict with Andrew's patch to switch hid-rmi
to use rmi4_core...
