i2c: designware: Mark dw_i2c_plat_{suspend,resume}() as __maybe_unused
When CONFIG_PM is set but CONFIG_PM_SLEEP is not, two compiler warnings
appear:
drivers/i2c/busses/i2c-designware-platdrv.c:444:12: error: unused function 'dw_i2c_plat_suspend' [-Werror,-Wunused-function]
static int dw_i2c_plat_suspend(struct device *dev)
^
drivers/i2c/busses/i2c-designware-platdrv.c:465:12: error: unused function 'dw_i2c_plat_resume' [-Werror,-Wunused-function]
static int dw_i2c_plat_resume(struct device *dev)
^
2 errors generated.
These functions are only used in SET_LATE_SYSTEM_SLEEP_PM_OPS(), which
is defined as empty when CONFIG_PM_SLEEP is not defined. Mark the
functions as __maybe_unused to make it clear that these functions might
be unused in this configuration.
