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.
