Description
In our driver, xhci scratchpads are fixed number, while later xhci 1.1 specs bumped them up. This results in an "Invalid number of scratchpads" error at boot.
xhci scratchpads need to be variable:

*cough* make that 1024. While my controller requested 36, the 1.1 spec says the controller can request up to 1023.

resolved via hrev50246.
1.1 spec bumped to 36. We actually are looking at number of scratch pads, but we had a low limit of 32 (which was the actual 1.0 count)
hrev50246 increased the maximum to a sane 48
