Bill Richardson d8b81cdc0f Cr50: Support USB on 15MHz FPGA image ...

The latest Cr50 FPGA release runs at 15MHz, but supports USB
operations. This CL includes changes to make that work.
Specifically:

* Enable the security features and select the correct PHY
* Adjust the turnaround time for the slower clock speed
* Handle the SET ADDRESS command specially for this SoC
* Remove all printfs from interrupt handlers (but add #ifdef code
  to print debug messages later if desired).

BUG=chrome-os-partner:34893
BRANCH=none
TEST=make buildall, manual test of Cr50 USB:

1. Plug into a USB jack on a Linux host.
2. In src/platform/ec/extra/usb_console, run

  make
  ./usb_console -p 5014 -e 1

3. Type something, hit return
4. See whatever you typed come back with swapped case
5. ^D to quit
