arm64: dts: qcom: sm8650-mtp: add gpio74 as reserved gpio

Browse Source 
The TLMM gpio74 is also used to communicate with the secure NFC
on-board module, some variants of the SM8650-MTP board 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.
