The memcpy like routines for moving to and from usb packet RAM couldn't deal with all unaligned uses, this fixes their behavior. In particular, a previous caller might assume that the packet RAM addresses were contiguous and attempt to break up a call into two separate chunks (as the queue insertion/removal code does). But this can lead to invalid pointers passed to these memcpy routines. A much cleaner solution is to make the packet RAM address space contiguous. To do so the memcpy routines take packet RAM addresses instead of AHB address space mapped addresses and __usb_ram_start needed to change to be of type usb_uint so that pointer arithmatic on it worked correctly on all platforms, this also allowed the usb_sram_addr macro to be simplified.
