[PATCH] i2c: nvidia-gpu: mark resume function as __maybe_unused

[Arnd Bergmann]

When CONFIG_PM is disabled, this is needed to avoid a harmless
unused-function warning:

drivers/i2c/busses/i2c-nvidia-gpu.c:345:12: error: 'gpu_i2c_resume' defined but not used [-Werror=unused-function]

Fixes: c71bcdcb42a7 ("i2c: add i2c bus driver for NVIDIA GPU")
