Set the interrupt de-bounce sampling cycle time based on the debounce counter clock source.
Example: _GPIO_SET_DEBOUNCE_TIME(GPIO_DBCTL_DBCLKSRC_LIRC, GPIO_DBCTL_DBCLKSEL_4).
It's meaning the De-debounce counter clock source is internal 10 KHz and sampling cycle selection is 4.
Then the target de-bounce sampling cycle time is (4)*(1/(10*1000)) s = 4*0.0001 s = 400 us, and system will sampling interrupt input once per 00 us.
