(re)merge r186415,186416 from the old usb stack;
o add Transaction Translator support (still missing ISOC xfers)
o add EHCI_SCFLG_BIGEMMIO flag to force big-endian byte-select to be
set in USBMODE
o split reset work into new public routine ehci_reset so bus shim drivers
can force big-endian byte-select before ehci_init
o enable TT and big-endian MMIO
o force a reset before ehci_init to get byte-select setup
Also go back to using USB_EHCI_BIG_ENDIAN_DESC at compile time to enable the
byteswapping and reduce diffs to the original commits.
This fixes the new USB stack on the Cambria board.
