[PATCH 07/10] USB: EHCI: make use of defines for descriptors

[Sebastian Hesselbarth]

Now that we have a full set of defines for each descriptor field,
make use of it for the EHCI HCD descriptors.

This fixes endianess issues for .device.bcdUSB, .device.bcdDevice,
.config.wTotalLength, and .endpoint.wMaxPacketSize.

Also, .endpoint.bInterval was set to 0 instead of 255 due to a
copy-and-paste error while assigning u8[] to usb_endpoint_descriptor.

This also is a preparation for including ch11.h later, which has
a modified usb_hub_descriptor for USB 3.0.
