arm64: kdump: identify memory regions
The following regions need to be identified for later use:
a) memory regions which belong to the 1st kernel
b) usable memory reserved for crash dump kernel
We go through /proc/iomem to find out a) and b) which are marked
as "System RAM" and "Crash kernel", respectively.
