Currently we allow all DAPM contexts to determine their own bias level. While this should in general work in most situations and will deliver the lowest possible power it causes problems for our integration with the card bias level as we're calling the card bias level functions for each DAPM context even though they're card wide but don't say which CODEC we're calling for. Mitigate against this by forcing everything to be in the same state.
