Instead of all drivers reading pci config space to get the revision
ID, they can now use the pci_device->revision member.
This exposes some issues where drivers where reading a word or a dword
for the revision number, and adding useless error-handling around the
read. Some drivers even just read it for no purpose of all.
In devices where the revision ID is being copied over and used in what
appears to be the equivalent of hotpath, I have left the copy code
and the cached copy as not to influence the driver's performance.

Switch the driver to always program DMA/PIO timings and set device transfer
mode instead of trusting BIOS on CSB6 controllers (libata pata_serverworks.c
driver is also doing things this way and there were no problems reported so
far). While doing conversion I noticed that the old code had many issues:
* the code was assuming that hwif->dma_status is always valid
(which obviously isn't true if hwif->dma_base == NULL)
* value of "(ultra_timing >> (4*unit)) & ~(0xF0)" expression wasn't checked
to fit into udma_modes[5]
* code validating DMA timings didn't validate corresponding PIO timings
* extra CSB5 PIO register wasn't validated et all
* hwif->ide_dma_off_quietly() is always called before ide_set_dma() (which in
turn calls hwif->speedproc() method - svwks_tune_chipset() in this case)
so the code depending on DMA capable bit of DMA status to be set was never
executed (=> the code was never validating DMA timings despite actually
enabling DMA if the PIO timings were OK!)
* on resume driver dependend entirely on BIOS to restore timings and set
transfer mode on the device
While at it:
There is no need to read PIO/MWDMA timings now so don't do it.
