wdc patch to get SSD with native SATA working on HP2133 netbook

Daniel C. Sinclair
As detailed in the following link I have to disable pciide and set my
BIOS to use SATA drives in 'compatible' mode in order to use my HP2133
netbook with the cheap 4GB SSD it came with:

http://www.nabble.com/Re%3A-Interrupt-problems-with-recent-snapshot-p20160942.html

I looked into the problem and discovered that my drive only supports
Ultra-DMA mode 4.  The pciide/wdc code forces various PIO/DMA settings
(including UDMA5) when it detects a SATA drive in 'native' mode and
dispenses with any autodetection.  The following patch just removes
the forced settings and lets the autodetection run.  My drive is
detected properly with my BIOS set to use native SATA and runs at a
more acceptable speed.  Presumably someone added that code because
some drives don't work with autodetection so I doubt this patch can be
applied to 4.6-beta without more widespread testing.

yes, i added it a long time ago as a workaround for some early seagate
sata drives. that time slow drives with sata interface didn't exist.

i don't mind to remove this hack but it needs some testing.
