[i-g-t v2 05/12] lib/intel_allocator: Add helper for getting allocator handle

[Bhanuprakash Modem]

From: Zbigniew Kempczyński <zbigniew.kempczynski at intel.com>

Allocator strategy for simple assigns offsets from the top to be
more malicious and exercise last bits in allocated offsets.

But for many cases we may want to create simple allocator with
allocating from the bottom of vm. Lets add some helper to do this
quickly in the code.
