USB: Add EHCI and OHCH glue for OCTEON II SOCs.
The OCTEON II SOC has USB EHCI and OHCI controllers connected directly
to the internal I/O bus. This patch adds the necessary 'glue' logic
to allow ehci-hcd and ohci-hcd drivers to work on OCTEON II.
The OCTEON normally runs big-endian, and the ehci/ohci internal
registers have host endianness, so we need to select
USB_EHCI_BIG_ENDIAN_MMIO.
The ehci and ohci blocks share a common clocking and PHY
infrastructure. Initialization of the host controller and PHY clocks
is common between the two and is factored out into the
octeon2-common.c file.
Setting of USB_ARCH_HAS_OHCI and USB_ARCH_HAS_EHCI is done in
arch/mips/Kconfig in a following patch.
