slc90e66: carry over fixes from piix driver
Synchronize with version 0.46 of the Intel PIIX/ICH driver:
- carry over Alan's and my own fixes in the tuneproc() method and my cleanups
both there and in the ratemask() method;
- SLC90E66 only supports MW DMA modes 1/2 and SW DMA mode 2 (just like Intel
chips), so don't claim support for other MW/SW DMA modes;
- don't check dor non-NULL drive->id in the ide_dma_check() method -- this is
assumed to be true in all other drivers;
- do some coding/formatting cleanups while at it...
