power-utils: Initially add isReadyToUpdate
Initially add isReadyToUpdate() that checks the pre-condition for PSU
update.
For now it only checks the power state and return false if power is on.
When it is not ready to update, there is no need to unbind/bind the
driver, so move the unbind/bind calls into doUpdate() from ctor/dtor.
Tested: Verify it returns and logs "PSU not ready to update" when power
is on, and continues the update when power is off.
