This commit makes the monitoring operations for the physical address
space and virtual address spaces register themselves to DAMON in the
subsys_initcall step. Later, in-kernel DAMON user code can use them via
damon_select_ops() without have to unnecessarily depend on all possible
monitoring operations implementations.
