Refactor how we interface with the root HUB. This cuts around 1200 lines of
code totally and saves one thread per USB bus.

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.

Clean up old way of polling the USB hardware. The existing polling support was
a bit hackish.
