Move clock enabling to the HAL

[bjoernQ]

Currently there is quite a lot of code just dealing with the clocks (basically what periph_module_reset(...), wifi_module_enable, wifi_module_disable, esp_wifi_bt_power_domain_on(), esp_wifi_bt_power_domain_off() do)

We can move that code the esp-hal and use it from there (since we deal with those things for other peripherals already there it makes sense to do that)
