[PATCH 05/17] pylibfdt: Add Property.as_*int*_array()

From: Luca Weiss <[email protected]>

Add new methods to handle decoding of int32, uint32, int64 and uint64
arrays.

This is a backport of dtc commit a04f69025003 ("pylibfdt: add
Property.as_*int*_array()"), without the dtc-side tests, which have no
counterpart in U-Boot's test suite.
