soc: intel_adsp/ace: linker: align cpuhold_* variables

Browse source 
For some weird unknown reasons, the simulator really do not
like the cpuhold_* variables to be tightly packed together.
This results in cpuhold_spawned not being updated, and we
will be stuck in the while loop for it to be set.
Workaround this by explicitly aligning these variables on
16 byte boundary. This seems to work for now.
