Vincent Palatin ebc973ce39 pd: log source current ...

Record what current limit we set when we act as a source
and when we are changing it.

The change should be backward-compatible as older EC will return 0 in
`current_max` when their role is PD_ROLE_SOURCE while newer firmware
will set the actual limit.

BRANCH=none
BUG=chrome-os-partner:56110
TEST=manual: on Kevin, plug and unplug various devices on the 2
ports, and dump the values with 'ectool usbpdpower'.
