sparc: parport: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

include/asm/parport.h is sparc64 specific. Rename it to parport_64.h and use the generic version for sparc32.
This fixed all{mod,yes}config build errors like:

The errors occur as the sparc32 build references sparc64 symbols.
