The TLMM gpio74 is also used to communicate with the secure NFC on-board module, some variants of the SM8650 QRD & MTP boards requires this GPIO to be dedicated to the secure firmware and set reserved in order to successfully initialize the TLMM GPIOs from HLOS (Linux). On the other boards this GPIO is unused so it's still safe to mark the GPIO as reserved.
