[PATCH 17/32 v4] USB: OHCI: remove PNX8550 OHCI driver

[Florian Fainelli]

The users have been converted to use the platform OHCI driver instead, thus
making the ohci-pnx8550 driver obsolete, so remove it.

Signed-off-by: Florian Fainelli <florian@xxxxxxxxxxx>

Changes in v4:
- rebased against greg's latest usb-next
