hpt34x: fix CONFIG_HPT34X_AUTODMA=n handling
Programming DMA mode may destroy current PIO mode setting so if
CONFIG_HPT34X_AUTODMA=n (the default case) make ide_tune_dma() fail
early by disabling all host DMA masks and re-tune PIO mode.
This fix doesn't help with the driver being broken but is needed
for some other changes.
