c430131a02 USB: EHCI: Support controllers with big endian capability regs
The two first HC capability registers (CAPLENGTH and HCIVERSION)
are defined as one 8-bit and one 16-bit register. Most HC
implementations have selected to treat these registers as part
of a 32-bit register, giving the same layout for both big and
small endian systems.

This patch adds a new quirk, big_endian_capbase, to support
controllers with big endian register interfaces that treat
HCIVERSION and CAPLENGTH as individual registers.

The ehci-sh driver was missing tie-ins for endpoint_reset and
clear_tt_buffer_complete, add them in.

c1e0774d74 usb: ehci-sh: Fix up fault in shutdown path.
We can't use the generic usb_hcd_platform_shutdown helper on account of
the fact we don't stash the hcd pointer in the driver data, so we provide
our own shutdown handler.

This adds a trivial stub for supporting EHCI mode of the on-chip
SH USB host controllers.
