sata_sil24: fix sg table sizing
sil24 unnecessarily used LIBATA_MAX_PRD and ATAPI sg table was short
by one entry which might cause very obscure problems. This patch
updates sg table sizing such that
* One full page is used for PRB + sg table. On 4k page,
this results in 253 sg's.
* Make ATAPI sg block properly sized.
* Make build fail if command block size doesn't equal PAGE_SIZE.
