    Clean up DMA timeout handling for HPT370:
    - hpt370_lostirq_timeout() cleared the DMA status which made __ide_dma_end()
       called afterwards return the incorrect result, and the DMA engine was reset
       both before and after stopping DMA while the HighPoint drivers only do it
       after (which seems logical) -- fix this and also rename the function;
    - get rid of the needless mutual recursion in hpt370_ide_dma_end() and
    - get rid of hpt370_lostirq_timeout() since hwif->ide_dma_end() called from
       the driver's interrupt handler later does all its work.
