drivers: wifi: nrfwifi: determine shared iovdd and bucken from dt 

Currently a user, or a shield definition, must select a Kconfig to
signal that the iovdd_ctrl and bucken GPIOs are connected to the same
pin. We can instead check this in the driver by simply checking if
the iovdd_ctrl_spec and bucken_spec are the same pin.

Update the nrfwifi driver and remove the redundant
NRF_WIFI_COMBINED_BUCKEN_IOVDD_GPIO config.

Enable this option to use a single GPIO to control both buck enable and IOVDD enable,
there will be a internal hardware switch to add delay between the two operations. This
is typically 4ms delay for nRF70.
