soc: nordic: nrf54h: Add option to use NFCT pins as GPIOs

Browse source 
Protection circuit must be disabled to use NFCT antenna pins
as GPIOs. It can be done by adding nfct-pins-as-gpios to nfct
node in the devicetree in cpuapp. Node must be disabled as
NFCT is not used. In legacy platforms same property was added
to uicr node because that information was stored in UICR. In
nrf54h20 it is not part of UICR so property is part of nfct
node.
