i2c: i2c-bfin-twi: add CONFIG_PM_SLEEP to suspend/resume functions
PATCH v2 7/7 i2c: i2c-bfin-twi: 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.
