Liav A 3547d90a0f Kernel/Storage: Select the drive before working with busmaster register 
This is a "quirk" I've observed on a Intel ICH7 test machine. Apparently
we need to select the device (master or slave) before starting to work
with the bus master register.
It's very possible that other machines are requiring this step to happen
before the DMA transfer can occur correctly.

Also, when reading with DMA, we should set the transfer direction before
clearing the interrupt status.

For the sake of completeness, I added a few lines in places that I
deemed it to be reasonable to clear the interrupt status there.
