i2c: designware: add CONFIG_PM_SLEEP to suspend/resume functions
Add CONFIG_PM_SLEEP to suspend/resume functions to fix the following
build warning when CONFIG_PM_SLEEP is not selected. This is because
sleep PM callbacks defined by SIMPLE_DEV_PM_OPS are only used when
the CONFIG_PM_SLEEP is enabled.
drivers/i2c/busses/i2c-designware-platdrv.c:211:12: warning: 'dw_i2c_suspend' defined but not used [-Wunused-function]
drivers/i2c/busses/i2c-designware-platdrv.c:221:12: warning: 'dw_i2c_resume' defined but not used [-Wunused-function]
