Subject: [PATCH net] net: phy: qca807x: fix compilation when CONFIG_GPIOLIB is not set

Kernel bot has discovered that if CONFIG_GPIOLIB is not set compilation
will fail.

Upon investigation the issue is that qca807x_gpio() is guarded by a
preprocessor check but then it is called under
if (IS_ENABLED(CONFIG_GPIOLIB)) in the probe call so the compiler will
error out since qca807x_gpio() has not been declared if CONFIG_GPIOLIB has
not been set.

Fixes: d1cb613efbd3 ("net: phy: qcom: add support for QCA807x PHY Family")
Reported-by: kernel test robot <lkp@...el.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202403031332.IGAbZzwq-lkp@intel.com/
