floppy: Drop unused pnp driver data

The pnp_device_id array is only used for module data to support
auto-loading the floppy module. So the .driver_data member is unused and
this assignment can be dropped.

While touching that array, align the coding style to what is used most
for these.

This patch doesn't modify the compiled array, only its representation
in source form benefits. The former was confirmed with x86 and arm64
builds.
