Get root device hints from the node object In order to support a more complex syntax for root device hints (e.g operators: greater than, less than, in, etc...) we need to stop relying on the kernel command line for passing the root device hints. This patch changes this approach by getting the root device hints from a cached node object that was set in the hardware module. Two new functions: "cache_node" and "get_cached_node" were added to the hardware module. The idea is to facilitate the access to a node object representation from the hardware extension methods without changing method signatures, which would break compatibility with out-of-tree hardware managers. Note that the new "get_cached_node" is just a guard function to facilitate the tests for the code. The function parse_root_device_hints() and its tests were removed since it's not used/needed anymore. Partial-Bug: #1561137 Change-Id: I830fe7da1a59b46e348213b6f451c2ee55f6008c

features:
- IPA now gets the root device hints directly from the node object
representation instead of the kernel command line. This is a required
work in order to support a more complex syntax for the hints in
the future.
