This patch is part of a series that extend the UHCI HCD to support
non-PCI host controllers.

This patch also extends the uhci_{read,write}* functions to allow accesses
to registers not mapped into PCI I/O space. This extension also includes
the addition of a void __iomem pointer to the uhci structure.

A new Kconfig option is added to signal that the system has a non-PCI HC.
If this Kconfig option is set, uhci-hcd.c will include generic reset functions
for systems that do not make use of keyboard and mouse legacy support. PCI
controllers will still always use the reset functions from pci-quirks

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.

Extends FSL EHCI platform driver glue layer to support
MPC5121 USB controllers. MPC5121 Rev 2.0 silicon EHCI
registers are in big endian format. The appropriate flags
are set using the information in the platform data structure.
MPC83xx system interface registers are not available on
MPC512x, so the access to these registers is isolated in
MPC512x case. Furthermore the USB controller clocks
must be enabled before 512x register accesses which is
done by providing platform specific init callback.

The MPC512x internal USB PHY doesn't provide supply voltage.
For boards using different power switches allow specifying
DRVVBUS and PWR_FAULT signal polarity of the MPC5121 internal
PHY using "fsl,invert-drvvbus" and "fsl,invert-pwr-fault"
properties in the device tree USB nodes. Adds documentation
