pdc202xx_new: remove useless code
Remove the following useless fragments from the driver:
- the ide_dma_lostirq() and ide_dma_timeout() handlers which boil down to just
printing the incoherent reset message and calling their default counterparts;
- check for non-NULL drive->id in the ide_dma_check() handler -- this is assumed
to be true by all other handlers (also, get rid of unnecessary nesting of the
conditional statements there);
- the comment before pdcnew_tune_drive() which has nothing to do with the code.
