The original version of the script worked but as the USB PD protocol
SM has been enhanced to handle more complicated scenarios the
occurrence of collisions on the baseband comm has grown and script
needs to account for that.
Script now checks status of ACK from zinger 'DONE 0' and retries two
additional times for commands that failed. If those three attempts
are unsuccessful script raises exception and quits.
Also added some more logging around retries and progress of chunk
writes.
BRANCH=none
BUG=chrome-os-partner:30135
TEST=manual, util/flash_pd.py build/zinger/ec.RW.flat succeeds in
programming zinger even in light of some retries.

Change the VDM implementation in the PD task to allow for VDMs
at any time when connected without disrupting any regular PD
communications.
BUG=none
BRANCH=none
TEST=load on a samus and on a zinger and test sending VDMs:
pd 0 flash version
pd 0 flash reboot
Also, test using the flash_pd.py script to write zinger RW using
VDMs.

Add console commands to send the Vendor-Defined Messages used to flash a
USB-PD target.
Also add a simple test script to flash Zinger through its CC line. To
run the script, the board must have CONFIG_USB_PD_CUSTOM_VDM defined.
By default fruitpie has this config option enabled.
BRANCH=none
BUG=chrome-os-partner:28330
TEST=With a fruitpie connected to a zinger run
./util/flash_pd.py ./build/zinger/ec.RW.flat
and see Zinger booting on RW.
