At present, the function that restores general purpose registers also
does ERET. Refactor the restore code to restore general purpose
registers without ERET to complement the save function.
The macro save_x18_to_x29_sp_el0 was used only once, and is therefore
removed, and its contents expanded inline for readability.
No functional changes, but with this patch:
- The SMC return path will incur an branch-return and an additional
register load.
- The unknown SMC path restores registers x0 to x3.
