USB: OHCI: remove ohci-pcc-soc driver.
This driver is not registered by any in-tree users, and if really needed by some out of tree user, the same functionnality can be restored using the ohci-platform driver using the following platform_data parameters: big_endian_desc = 1 big_endian_mmio = 1 no_big_frame_no = 1 Signed-off-by: Florian Fainelli <florian@openwrt.org> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
