refactor(arm): simplify early platform setup functions

Browse source 
Refactor `arm_sp_min_early_platform_setup` to accept generic
`u_register_r` values to support receiving firmware handoff boot
arguments in common code. This has the added benefit of simplifying the
interface into common early platform setup.
