The usb_lowlevel_init() call already fills and passes back struct
ehci_ctrl , which readily contains correctly determined address of
the port register block address computed from values from controller
configuration registers. Leverage this and make use of this value
as this makes the code mode universal, but also gets us rid of the
CONFIG_USB_REG_BASE configuration option.
Moreover, this patch cleans up the usb_gadget_register_driver() call
a little by correcting the error handling. Note the usb_lowlevel_init()
and mvudc_probe() are now called in reversed order, but this has no
impact on the code.

Move the constant values that are programmed into mv_ep.ep into
separate static const structure so they can be memcpy()'d when
the initialization happens.
Moveover, we only every init NUM_ENDPOINTS, not 2 * NUM_ENDPOINTS,
so fix this bug as well.

The endpoints are operated on a per-controller basis, move the

struct mv_ep structure definition just above the definition of

This patch adds support to both Faraday FUSBH200 and FOTG210,
the differences between Faraday EHCI and standard EHCI are
listed bellow:
1. The PORTSC starts at 0x30 instead of 0x44.
2. The CONFIGFLAG(0x40) is not only un-implemented, and
also has its address space removed.
3. Faraday EHCI is a TDI design, but it doesn't
compatible with the general TDI implementation
found at both U-Boot and Linux.
4. The ISOC descriptors differ from standard EHCI in
several ways. But since U-boot doesn't support ISOC,
we don't have to worry about that.
