[PATCH 02/32] USB: OHCI: remove ohci-pcc-soc driver.

[Florian Fainelli]

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
