nfc_fixes.h refers to dev.kit instead of chip variant

[FormerMember]

In file nfc_fixes.h, SDK 15.0.0:

#ifdef BOARD_PCA10040           // assume nRF52832 chip in IC rev. Engineering B or Engineering C

    #define HAL_NFC_ENGINEERING_BC_FTPAN_WORKAROUND

#elif defined(BOARD_PCA10056)   // assume nRF52840 chip in IC rev. Engineering A

    #define HAL_NFC_NRF52840_ENGINEERING_A_WORKAROUND

#endif

The workarounds are based on the dev.kit boards and not the chip variant. Be aware of this when using custom board.
