sata_sil24: fix kernel panic on ARM caused by unaligned access in sata_sil24
The sata_sil24 driver has six 16-bit registers that are initialised with
32-bit writes. This cause a kernel panic on ARM due to the unaligned
accesses which result.
This patch changes the accesses to the correct 16-bit ones.
