[PATCH] net: aquantia: fix undefined devm_hwmon_device_register_with_info reference

[Kefeng Wang]

drivers/net/ethernet/aquantia/atlantic/aq_drvinfo.o: In function `aq_drvinfo_init':
aq_drvinfo.c:(.text+0xe8): undefined reference to `devm_hwmon_device_register_with_info'

Fix it by using #if IS_REACHABLE(CONFIG_HWMON).
