Alec Berg f7ed411926 pd: allow sink to request new voltage w/o dropping negotiation ...

Allow a sink to request a new voltage without dropping the established
negotiation. For this to work the sink must save the last received
source cap packet and use that to make a new RDO from the SNK_READY
state.

BUG=chrome-os-partner:30389
BRANCH=none
TEST=Tested on a firefly connected to zinger. made sure we can press
buttons to change voltage and we don't lose the existing negotiation.
Also tested on samus, ports 0 and 1, using pd x dev 5/12/20 to switch
between voltages and verified we don't lose existing negotiation.
