6dd30af0fa usb: mv_udc: Add bounce buffer
The requests sent to the controller are not properly cache aligned
most of the time, thus implement a simple bounce buffer to avoid
problem with cache.

8a095a68ce usb: mv_udc: Improve allocation of qTD items
Allocate the qTD items all at once instead of allocating them
separately. Moreover, make sure each qTD is properly aligned
to 32-bytes boundary and that cache can be safely flushed over
each qTD touple.

ab52df19c1 usb: mv_udc: Move QH and qTD into mv_drv
Both the endpoint queue head and the endpoint item list is a controller
specific thing. Move them both into controller private data.

be7ed2533d usb: mv_udc: Make use of struct ehci_ctrl
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.

2ea4b44832 usb: mv_udc: Clean up the EP initialization
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.

532d846f89 usb: mv_udc: Move endpoint array into driver data
The endpoints are operated on a per-controller basis, move the
endpoint array into controller's private data. Also shuffle the
struct mv_ep structure definition just above the definition of
the struct mv_drv so they're well grouped together.

Do a coding-style cleanup of this file and throw away useless
defined values. These values were likely a result of a copy-paste
job.

c7e3b2b586 usb: lowlevel interface change to support multiple controllers
Carry an index in the lowlevel usb functions to make specify the
respective usb controller.

Also pass through an controller struct from lowlevel_init to the
creation of the root usb device of this controller.
