Yes, such a change is clearly wrong. Jim, you have access to the
schematics for all these boards. Please use them.

The correct values are:

Beaver:

USB1 VBUS: PEX_L1_CLKREQ / PDD6 / 238
USB3 VBUS: PEX_L1_PRSNT / PDD4 / 236

Incorrect: GMI_AD13 / PH5 / 61
(This is a signal that pulls up all of USB1 VBUS, USB3 VBUS, and
GMI_AD15, which as far as I can tell is entirely unrelated to USB in
any way)

Cardhu A04:

USB1 VBUS: PEX_L1_CLKREQ / PDD6 / 238
USB3 VBUS: PEX_L1_PRSNT / PDD4 / 236

Incorrect: PEX_L0_RST / PDD1 / 233
(This is a signal that pulls up a whole slew of signals, many of which
are entirely unrelated to USB in any way)
