greybus: power_supply: invalidate cache at update request
When we receive a update request we shall not trust the cache mechanism and for that we need a way to invalidate the cache. Add a field that will control the cache status and refactor the code to check if cache is valid in a helper function. This will fix the scenario where an update request is received within the cache expiration time after a previous update as happened and would be ignored.
