This has the advantage of always compiling these functions in, independently of any Kconfig option. Thanks to that, bugs and other regressions are subsequently easier to catch. The pl061_context_save_regs structure is always embedded into struct pl061 to simplify code, so this brings a tiny 8 bytes memory overhead for !CONFIG_PM_SLEP.
