iio: gyro: st_gyro: Mark gyro_pdata with __maybe_unused

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 gyro_pdata with __maybe_unused to calm a compiler down:

In file included from drivers/iio/gyro/st_gyro_i2c.c:18:
