AArch64: Refactor GP register restore to separate function
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.
