/**
* @brief Set glitch filter for PCNT unit
*
* @note The glitch filter module is clocked from APB, and APB frequency can be changed during DFS, which in return make the filter out of action.
* So this function will lazy-install a PM lock internally when the power management is enabled. With this lock, the APB frequency won't be changed.
* The PM lock can be uninstalled in `pcnt_del_unit()`.
* @note This function should be called when the PCNT unit is in the init state (i.e. before calling `pcnt_unit_enable()`)
*
* @param[in] unit PCNT unit handle created by `pcnt_new_unit()`
