[PATCH 16/32 v4] MIPS: PNX8550: use OHCI platform driver

From: Florian Fainelli
Date: Mon Oct 08 2012 - 09:18:55 EST


Change the PNX8550 platform code to register an ohci-platform driver instead
of ohci-pnx8550 since the ohci-platform is suitable for use.

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

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