I've modified sata_rcar_bmdma_fill_sg() to take care of splitting long
scatter/ gather segments due to the descriptor table transfer counter
being only 28 bits wide (bit 1 to bit 28) but that was in vain as even
if 'sata_rcar_sht' specified a correct 'dma_boundary' field, the DMA
and block layers would have split the S/G segments on the necassary
boundaries. Since the driver uses ATA_BMDMA_SHT() to initilaize
'sata_rcar_sht', the boundary is much smaller, only 0xFFFF, so the
code I've added is even more useless, and it's better to just remove
it.

Use the wrapper functions for getting and setting the driver data using
platform_device instead of using dev_{get,set}_drvdata() with &pdev->dev,
so we can directly pass a struct platform_device.
Also, unnecessary dev_set_drvdata() is removed, because the driver core
clears the driver data to NULL after device_release or on probe failure.

Use the newly introduced devm_ioremap_resource() instead of
devm_request_and_ioremap() which provides more consistent error handling.
