Hidden function to indicate that that the soc_secure functions are
available.
The functions are always available when not in non-secure.
For non-secure the functions must redirect to secure services exposed
by the secure firmware.

enable building with TF-M as the Secure Execution Environment.

depends on $(dt_has_compat,$(DT_COMPAT_NORDIC_NRF_NFCT))
select DEPRECATED
help
Two pins are usually reserved for NFC in SoCs that implement the
NFCT peripheral. This option switches them to normal GPIO mode.
HW enabling happens once in the device lifetime, during the first
system startup. Disabling this option will not switch back these
pins to NFCT mode. Doing this requires UICR erase prior to
flashing device using the image which has this option disabled.
NFC pins in nRF52 series: P0.09 and P0.10
NFC pins in nRF5340: P0.02 and P0.03
This option is deprecated, please use devicetree to configure NFCT
pins as GPIOS like this:
&uicr {
nfct-pins-as-gpios;
};

When this option is selected, the SystemInit() function loads the
firmware branch state of the APPROTECT mechanism from UICR, so if
UICR->APPROTECT is disabled, CTRLAP->APPROTECT will be disabled.
