iio: accel: BMC150: fix issues when CONFIG_PM_RUNTIME is not set
When CONFIG_PM_RUNTIME is not set, the following issues are seen:
* warning message at compilation time:
warning: 'bmc150_accel_get_startup_times' defined but not used [-Wunused-function]
* bmc150_accel_set_power_state() will always fail and reading the
accelerometer data is impossible;
This occurs because of the call to pm_runtime_put_autosuspend calls
__pm_runtime_suspend which returns -ENOSYS.
This commit fixes these.
