[RESEND PATCH net-next v3] net: smc91x: Fix pointer types

[Thorsten Blum]

Use void __iomem pointers as parameters for mcf_insw() and mcf_outsw()
to align with the parameter types of readw() and writew() to fix the
following warnings reported by kernel test robot:

Changes in v2:
- Use lp->base instead of __ioaddr as suggested by Andrew Lunn. They are
 essentially the same, but using lp->base results in a smaller diff
- Remove whitespace only changes as suggested by Andrew Lunn
- Preserve Acked-by: Nicolas Pitre tag
- Link to v1: https://lore.kernel.org/linux-kernel/20240516121142.181934-3-thorsten.blum@xxxxxxxxxx/

Changes in v3:
- Revert changing the macros as this is unnecessary. Neither the types
  nor the __iomem attributes get lost across macro boundaries
- Preserve Reviewed-by: Andrew Lunn tag
- Link to v2: https://lore.kernel.org/linux-kernel/20240516155610.191612-3-thorsten.blum@xxxxxxxxxx/
