  3. core: add support for transfer list 

    Add supports for Transfer List on both aarch32/64.
Fetch arguments from {x,r}{0-3} and check if a valid Transfer List
exists, which compliant to the Firmware Handoff specification.
The Transfer List will be mapped during early initialization and
unmapped before exiting to next boot stage.
DTB and pagable address will be parsed from the Transfer List if
they exist as Transfer Entries.
If Transfer List does not exist or is invalid, legacy argument
handoff is backwards compatible.
