nocturne: Add board_set_tcpc_power_mode().
When depthcharge needs to update the TCPCs, it needs to reset them at
the end of the update procedure. Conveniently, this function will be
called if it exists, therefore this commit implements that function. It
simply resets the TCPCs and then waits about 50ms for the part to come
up.
BUG=b:69010531
BRANCH=None
TEST=With other patches, flash nocturne; verify that TCPC FW can be
updated.
