[PATCH] PCI: rockchip: mark PM functions as __maybe_unused

[Arnd Bergmann]

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")
