Vic Yang 142b0073bc Set proper value for BOOTCFG ...

We choose PE2/USB1_CTL1 for BOOTCFG. If we somehow brick the EC, we can
pull this signal to ground and boot EC into boot loader to recover it.

BUG=chrome-os-partner:8769
TEST=On link:
      - Factory reset EC to clear BOOTCFG
      - Flash new EC binary and reboot
      - rw 0x400fe1d0 to check BOOTCFG value is correctly written
      - Boot normally and check EC is operating correctly
      - Pull the signal to ground and reset EC, check EC stays in boot
        loader. Check in this case we can program EC.
      - Attempt to write different value to BOOTCFG and check BOOTCFG
	doesn't change.
