There was a recent change to save the manual setting of charge current and voltage, however it was done so assuming that the parameters were set via the host command interface. (CL:922069) However, there are times where the charge voltage/current would like to be manipulated without booting the AP. This commit simply makes the EC console command work again. BUG=None BRANCH=None TEST=make -j buildall TEST=Flash nocturne, `chgstate idle on; charger current 256; charger voltage 7400`; verify that the charge voltage and current is actually changed.
