gpio: pca9570: rename platform_data to chip_data

Browse source 
By convention platform_data refers to structures passed to drivers by
code that registers devices. When talking about model-specific data
structures associated with OF compatibles, we usually call them chip_data.

In order to avoid confusion rename all mentions of platform_data to
chip_data.
