hpt366: UltraDMA filter for SATA cards (take 2)

The Marvell bridge chips used on HighPoint SATA cards do not seem to support
the UltraDMA modes 1, 2, and 3 as well as any MWDMA modes, so the driver needs
to account for this in the udma_filter() method.  In order to achieve that, do
the following changes:

- install the method for all chips, not only HPT36x/370 and improve the code
  formatting by killing the extra tabs while at it;

- add to the end of the 'switch' statement in the method cases for HPT372[AN]
  and HPT374 chips upon which the known SATA cards are based;

- use hwif->ultra_mask as a default mask for the ide_dma_filter() method to
  behave correctly;

- move the HPT370[A] cases below the HPT36x case for consistency.

While at it, replace the explicit UltraDMA mode masks with ATA_UDMA* constants
all over the driver...
