Commit b416191a14 (Fix EHCI port reset.) didn't
move the code that checked for successful clearing of the port reset bit from
ehci_submit_root(), relying on wait_ms() call instead. The mentioned code also
erroneously reported port reset state when the reset was already completed.

USB devices on the 2nd port are not detected and I get the following message:
The request port(1) is not configured
That's with default CONFIG_SYS_USB_EHCI_MAX_ROOT_PORTS value of 2. 'req->index'
is 1-based, so the comparison in ehci_submit_root() can't be correct.

On little endian machines, EHCI root hub's USB revision is reported as 0.2 --
cpu_to_le16() was missed in the initializer for the 'bcdUSB' descriptor field.
The same should be done for the 'bcdDevice' field.

This patch is part of migrating the AT91 support towards
using C struct for all SOC access.
It removes one more CONFIG_AT91_LEGACY warning.
at91_pmc.h needs cleanup after migration of the drivers
has been done.

The conversion from offsets to C structs lost a little padding in the DMA
register map. Accessing endpoints other than ep0 with DMA would fail as
the addresses wouldn't be adjusted correctly.

SPEAr SoCs contain a synopsys usb device controller.
USB Device IP can work in 2 modes
- DMA mode
- Slave mode
The driver adds support only for slave mode operation of usb
device IP. This driver is used along with standard USBTTY
driver to obtain a tty interface over USB on the host

In USB ehci driver, the port reset is not terminated. EHCI spec says "A host
controller must terminate the reset and stabilize the state of the port within
2 milliseconds". Without termination, a port stays at reset state. This is
observed on ppc4xx(sequoia) boards.

The RX Control/Status register has bits that we want to preserve, so don't
just write out a single bit. Preserve the others bits in the process.
The original code posted to the u-boot list had this behavior, but looks
like it was lost somewhere along the way to merging.

The dynamic FIFO handling under MUSB is optional, and some parts (like
the Blackfin processor) do not implement support for it.
Due to this, the FIFO reading/writing steps need special handling, so
mark the common versions weak so drivers can override.

The header files usb.h and usbdescriptors.h have the same nameed
structure definitions for
usb_config_descriptor
usb_interface_descriptor
usb_endpoint_descriptor
usb_device_descriptor
usb_string_descriptor
These are out right duplicates in usb.h
usb_device_descriptor
usb_string_descriptor
This one has extra unused elements
usb_endpoint_descriptor
unsigned char bRefresh
unsigned char bSynchAddress;
These in usb.h have extra elements at the end of the usb 2.0
specified descriptor and are used.
usb_config_descriptor
usb_interface_descriptor
The change is to consolidate the definition of the descriptors
to usbdescriptors.h. The dublicates in usb.h are removed.
The extra element structure will have their name shorted by
removing the '_descriptor' suffix.
So
usb_config_descriptor -> usb_config
usb_interface_descriptor -> usb_interface
For these, the common descriptor elements are accessed now
by an element 'desc'.
As an example
- if (iface->bInterfaceClass != USB_CLASS_HUB)
+ if (iface->desc.bInterfaceClass != USB_CLASS_HUB)
This has been compile tested on MAKEALL arm, ppc and mips.

So far the console API uses the following naming convention:
======Extract======
typedef struct device_t;
int device_register (device_t * dev);
int devices_init (void);
int device_deregister(char *devname);
struct list_head* device_get_list(void);
device_t* device_get_by_name(char* name);
device_t* device_clone(device_t *dev);
=======
which is too generic and confusing.
Instead of using device_XX and device_t we change this
into stdio_XX and stdio_dev
This will also allow to add later a generic device mechanism in order
to have support for multiple devices and driver instances.
