Add CONFIG_PM_SLEEP to suspend function 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-puv3.c:255:12: warning: 'puv3_i2c_suspend' defined but not used [-Wunused-function]
