gpiolib: Mark gpio_suffixes array with __maybe_unused
[ Upstream commit b23ec59926faf05b0c43680d05671c484e810ac4 ]
Since we put static variable to a header file it's copied to each module
that includes the header. But not all of them are actually used it.
Mark gpio_suffixes array with __maybe_unused to hide a compiler warning:
