Many chips require 64-bit variables to display the accumulated energy, even more so since the energy units are micro-Joule. Add new sensor type "energy64" to support reporting the chip energy as 64-bit values. Changing the entire hardware monitoring API is not feasible, and it is only really necessary to support reading 64-bit values for the "energyX_input" attribute. For this reason, keep the API as-is and use type casts on both ends to pass 64-bit pointers when reading the accumulated energy. On the write side (which is only useful for the energyX_enable attribute), keep passing the written value as long.
