arm64: dts: sdm845-mtp: Reserve reserved gpios
With the introduction of commit 3edfb7bd76bd ("gpiolib: Show correct direction from the beginning") the gpiolib will attempt to read the direction of all pins, which triggers a read from protected register regions. The pins 0 through 3 and 81 through 84 are protected, so mark these as reserved.
