[PATCH v5 0/8] arm64, numa: Add numa support for arm64 platforms.

[Ganapatrao Kulkarni]

v5:
	- created base verion of numa.c which creates dummy numa without using dt
	  on single socket platforms. Then added patches for dt support.
	- Incorporated review comments from Hanjun Guo.

v4:
done changes as per Arnd review comments.

v3:
Added changes to support numa on arm64 based platforms.
Tested these patches on cavium's multinode(2 node topology) platform.
In this patchset, defined and implemented dt bindings for numa mapping
for core and memory using device node property arm,associativity.

v2:
Defined and implemented numa map for memory, cores to node and
proximity distance matrix of nodes.

v1:
Initial patchset to support numa on arm64 platforms.

Note:
	1. This patchset is tested for numa with dt on
	   thunderx single socket and dual socket boards.
	2. Numa DT booting needs the dt memory nodes, which are deleted in current efi-stub,
	hence to try numa with dt, you need to rebase with ard's patchset.
