USB: descriptor handling

Hi,

I found a bug when working with the u-boot USB subsystem on IXP425 processor
(big endian Xscale aka ARMv5).
I recognized that the second usb_endpoint_descriptor of the attached memory
stick was corrupted.

The reason for this are the packed structures below (either u-boot and
u-boot-usb):

--------------
/* Endpoint descriptor */
struct usb_endpoint_descriptor {
unsigned char bLength;
unsigned char bDescriptorType;
unsigned char bEndpointAddress;
unsigned char bmAttributes;
unsigned short wMaxPacketSize;
unsigned char bInterval;
unsigned char bRefresh;
unsigned char bSynchAddress;

} __attribute__ ((packed));
/* Interface descriptor */
struct usb_interface_descriptor {
unsigned char bLength;
unsigned char bDescriptorType;
unsigned char bInterfaceNumber;
unsigned char bAlternateSetting;
unsigned char bNumEndpoints;
unsigned char bInterfaceClass;
unsigned char bInterfaceSubClass;
unsigned char bInterfaceProtocol;
unsigned char iInterface;

unsigned char no_of_ep;
unsigned char num_altsetting;
unsigned char act_altsetting;
struct usb_endpoint_descriptor ep_desc[USB_MAXENDPOINTS];
} __attribute__ ((packed));
------------

As usb_endpoint_descriptor is only 7byte in length, the start of all
odd ep_desc[] structures is not word aligned. This makes wMaxPacketSize
of these structures also not word aligned.

ARMv5 Architecture however does not support non-aligned multibyte
data type (see A2.8 of ARM Architecture Reference Manual).

fix USB initialisation procedure

The max packet size is encoded as 0,1,2,3 for 8,16,32,64 bytes.
At some places directly 8,16,32,64 was used instead of the encoded
value. Made a enum for the options to make this more clear and to help
preventing similar errors in the future.

After fixing this bug it became clear that another bug existed where
the 'pipe' is and-ed with PIPE_* flags, where it should have been
'usb_pipetype(pipe)', or even better usb_pipeint(pipe).

Also removed the triple 'get_device_descriptor' sequence, it has no use,
and Windows nor Linux behaves that way.
There is also a poll going on with a timeout when usb_control_msg() fails.
However, the poll is useless, because the flag will never be set on a error,
because there is no code that runs in a parallel that can set this flag.
Changed this to something more logical.

Tested on AT91SAM9261ek and compared the flow on the USB bus to what
Linux is doing. There is no difference anymore in the early initialisation
sequence.
