Subject: [PATCH] [PATCH] ide_dma_speed() fixes

ide_dma_speed() fails to actually honor the IDE drivers' mode support
masks) because of the bogus checks -- thus, selecting the DMA transfer mode
that the driver explicitly refuses to support is possible.  Additionally,
there is no check for validity of the UltraDMA mode data in the drive ID,
and the function is misdocumented.
