Add CONFIG_PM_RUNTIME to i2c_dw_pci_runtime_idle() to fix the
build warning when CONFIG_PM_RUNTIME is not selected. This is
because runtime PM callbacks defined by SET_RUNTIME_PM_OPS are
only used when the CONFIG_PM_RUNTIME is enabled.

drivers/i2c/busses/i2c-designware-pcidrv.c:188:12: warning: 
'i2c_dw_pci_runtime_idle' defined but not used [-Wunused-function]
