plat/common: move arch-agnostic fallback functions to C file
When we add a new callback, we need to duplicate fallbacks among
plat/common/{aarch32,aarch64}/platform_helpers.S This is tedious.
I created a new C file, then moved 3 functions:
plat_error_handler
bl2_plat_preload_setup
plat_try_next_boot_source
They are called from C, so I do not see a good reason to implement
them in assembly.
