PCI: rockchip: Mark PM functions as __maybe_unused
When CONFIG_PM_SLEEP is disabled, we get harmless build warnings:
host/pcie-rockchip.c:1267:12: error: 'rockchip_pcie_resume_noirq' defined but not used [-Werror=unused-function]
host/pcie-rockchip.c:1240:12: error: 'rockchip_pcie_suspend_noirq' defined but not used [-Werror=unused-function]
Marking both functions as __maybe_unused avoids the warning without the
need for #ifdef around them.
Fixes: 013dd3d5e183 ("PCI: rockchip: Add system PM support")
