Subject: [PATCH 08/18] gpio: mockup: pass the named_lines parameter over platform_data

Move the last bits of code dealing with module parameters to the init
function. Add a new variable to platform data, which indicates to the
probe function if it should name the GPIO lines. If we ever want to
make the line naming more fine-grained (e.g. per chip switch) it will
be easier this way.
