What is the gpio Number is G8 and F7 pin at TX2?
G8=GPIO3_PR.00=178=136
F7=GPIO3_PN.02=138+2=114+2=116
is right?
GPIO0_CAM0_PWR# G8 QSPI_SCK GPIO3_PR.00
GPIO1_CAM_PWR# F7 GPIO_CAM3 GPIO3_PN.02

Assuming your Main Tegra GPIO chip is getting mapped to the base GPIO # 320:
GPIO3_PR.00 = 456
GPIO3_PN.02 = 426
You can check this on your console log as the kernel boots. Or you can go into your /sys/class/gpio folder and look at the gpiochipsXXX that are enumerated.
You should see this for the Tegra Main GPIOs:
$ cat /sys/class/gpio/gpiochip320/device/modalias;echo
of:NgpioTCnvidia,tegra186-gpio
You should see this for the Tegra AON GPIOs:
$ cat /sys/class/gpio/gpiochip256/device/modalias;echo
of:NgpioTCnvidia,tegra186-gpio-aon
Here is an easy table you can use to find the number given the PORT and # of the GPIO:
