soc: nordic_nrf: move NFCT_PINS_AS_GPIOS to common nRF definitions

Browse source 
Kconfig symbol NFCT_PINS_AS_GPIOS may be defined for all
Nordic nRF SoCs that have the NFCT hardware, so we move
the option definition in nRF common Kconfig file. Also,
we correct the help text to reflect that nRF52 series DKs
and nRF5340 DK have different pins for NFC.

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.
