FUJITA Tomonori f3506b755f [SCSI] 53c700: remove dma_is_consistent usage 
This driver is the only user of dma_is_consistent(). We plan to remove
this API.

The driver uses the API in the following way:

BUG_ON(!dma_is_consistent(hostdata->dev, pScript) && L1_CACHE_BYTES < dma_get_cache_alignment());

The above code tries to see if L1_CACHE_BYTES is greater than
dma_get_cache_alignment() on sysmtes that can not allocate coherent
memory (some old systems can't).

James Bottomley exmplained that this is necesary because the driver
packs the set of mailboxes into a single coherent area and separates
the different usages by a L1 cache stride. So it's fatal if the dma
coherence stride is greater than the L1 cache size.

He also pointed out that we can kill this checking because we don't
hit this BUG_ON on all architectures that actually use the driver.
