previously, we asked the user to enable the gpio direction before
initialize the dedicated GPIO.
Now the dedicated GPIO driver will help enable the input/output path
according to the in_en and out_en flags.
This commit moves the dedicated GPIO LL and HAL functions from
cpu_ll.h to dedic_gpio_cpu_ll.h.
- cpu_ll_enable_cycle_count() has also been removed due to lack of feasible usage scenarios
