hwmon: Only include of_match_table with CONFIG_OF_GPIO
The following fixes build errors on sparc. Without any DT support, of_match_ptr is NULL and the below is a no-op. However, if just CONFIG_OF is defined then so is of_match_ptr. All useful parts of the gpio-fan DT support rely on CONFIG_OF_GPIO anyway, so of_match_table should too.
