George Oikonomou 421fbfae25 Change the LPM locks API:
Instead of using a separate data structure to request that a PD remain powered during deep sleep,
we do the same within the main LPM data structure through an additional field.

This allows us to maintain only one linked list of LPM modules and overall improves code clarity
