pdc202xx_new: remove useless code

Browse Source 
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.
