[PATCH 05/19] ata: ide-sff: fix warnings when compiling as 64-bit

Driver is applicable to both IDEs with I/O port and MMIO control. This
is differentiated by ide->io.mmio. Compiler can't follow that and
criticizes casting pointers to 32-bit integers on 64-bit architectures.
Adjust the casts to silence this false positive.
