smb-lib: revert the boost back workaround for dc path
It is expected to get 3 switcher-power-ok interrupts in a span of 1
second for Wipower. This causes the boost back workaround to suspend
dc path.
The boost back problem was never seen on Wipower. Revert the boost
back workaround for Wipower until a proper fix is in place.
