[PATCH 7/7] EmbeddedPkg: SiI3132: Correct the IoAlign

[Jeremy Linton <jeremy.linton@arm.com>]

With the update to the DMA lib, and the FIS submission
cleanups the SiI driver now works fine with alignments
less than a full page. Large alignment requirements
cause problems with grub. Decrease it to a sane value.
