USB PD: Report operating power in sink capabilities
Currently, the vSafe5V sink capability response reports desiring a flat
500mA for every board. This is out of sync with the battery and variable
capabilities, which report requiring our defined operating power or
maximum current. Change the 500mA to the operating power divided over 5
volts, or the maximum current (whichever is smaller).
BRANCH=None
BUG=b:179423663
TEST=on voxel, confirm sink capabilities report wanting 3.0A for vSafe5V
and confirm drawcia will offer 3.0A when voxel charges
