arm64: ptdump: Allow all region boundaries to be defined at boot time

Rework the way the address_markers array is populated so that we can
tolerate values that are not compile time constants generally, rather
than keeping track manually of the array indexes in question, and poking
new values into them manually. This will be needed for VMALLOC_END,
which will cease to be a compile time constant after a subsequent patch.
