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.

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

The ASIX driver calls a basic_init() function during get_info(), so that
not all initialization tasks need to be redone on every init().
Unfortunately, the most important one is still triggered too often: the
driver does a full port and MII reset on every asix_init(), requiring up
to several seconds to reestablish the link.
This patch confines that software reset into the asix_basic_init()
function so that it will only be executed once. This saves about a
second of boot time on systems using BOOTP.
Note: this patch was previously submitted many moons ago as:
usb: usbeth: asix: Do a fast init if link already established

This happens with dfu-util (debian version: 0.5), which address non standard

Without this fix, the above request is STALLED, and hence causes dfu-util

In turn it displays following errors:

It seems that on AM35X interrupt status registers can be updated

Linux usb/ch9.h seems to have all the same information (and more)
as usbdescriptors.h so use the former instead of the later one.
As a consequense of this change USB_SPEED_* values don't correspond
directly to EHCI speed encoding anymore, I've added necessary
recoding in EHCI driver. Also there is no point to put speed into
pipe anymore so it's removed and a bunch of host drivers fixed to
look at usb_device->speed instead.
Old usbdescriptors.h included is not removed as it seems to be
used by old USB device code.
This makes usb.h and usbdevice.h incompatible. Fortunately the
only place that tries to include both are the old MUSB code and
it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute
on musb_regs structure but this attribute seems to be unneeded
(old MUSB code doesn't support any DMA at all).

The correct bit for H1_PM is 16, not 8, which is the DP pull-up impedance
selection bit.
This issue has been reported by Eric Bénard <eric@eukrea.com> and fixed by
Christoph Fritz <chf.fritz@googlemail.com> on Linux, from which these #define-s
had been copied.

A custom board_ehci_hcd_init() may be unneeded, so add a weak default
implementation doing nothing.
By the way, use simple __weak from linux/compiler.h for
board_ehci_hcd_postinit() instead of weak alias with full attribute.

Some MXC SoCs like the i.MX35 have hosts located at unusual offsets, so prepare
to the introduction of i.MX35 support by defining the ehci-mxc hosts offsets at
SoC level.

Make EHCI power and overcurrent polarities configurable. If not set, these new
configurartions keep the default register values so that existing board files
do not have to be changed.

The i.MX53 has MXC_H*_UCTRL_H*_OC_DIS_BIT bits to disable the oc pin.

MXC_OTG_UCTRL_OPM_BIT disables (masks) the power/oc pins if set, like
MXC_H1_UCTRL_H1PM_BIT and MXC_H2_UCTRL_H2PM_BIT, not the opposite.
