8250: mediatek: mark PM functions as __maybe_unused
The mtk8250_runtime_suspend function is not used when runtime PM is
disabled, so we get a warning about an unused function:
drivers/tty/serial/8250/8250_mtk.c:119:12: error: 'mtk8250_runtime_suspend' defined but not used [-Werror=unused-function]
static int mtk8250_runtime_suspend(struct device *dev)
This marks all the PM functions as __maybe_unused to avoid the warning,
and removes the #ifdef around the PM_SLEEP functions for consistency.
