arm: Switch aarch64 to using generic global_data setup
There is quite a bit of assembler code that can be removed if we use the generic global_data setup. Less arch-specific code makes it easier to add new features and maintain the start-up code. Drop the unneeded code and adjust the hooks in board_f.c to cope. Tested on LS2085ARDB and LS2085AQDS (armv8 SoC).
