Commit f67213cee2b3 ("phy: tegra: xusb: Add usb-role-switch support") added `select USB_CONN_GPIO` to PHY_TEGRA_XUSB to support USB role switching via GPIO-based detection. At that time, PHY_TEGRA_XUSB depended only on `ARCH_TEGRA`, and both the ARM32 and ARM64 ARCH_TEGRA Kconfig definitions select GPIOLIB, so the missing explicit GPIOLIB guard was not a functional problem — GPIOLIB is always available when ARCH_TEGRA is enabled. Later, commit 0d5c9bc7c680 ("phy: tegra: Select USB_COMMON for usb_get_maximum_speed()") added `depends on USB_SUPPORT` but still did not address the GPIOLIB gap. The select can force USB_CONN_GPIO on without its GPIOLIB dependency being satisfied if the Kconfig dependencies were ever restructured. Make the select conditional with `select USB_CONN_GPIO if GPIOLIB` to make the dependency explicit. This mirrors how other drivers handle optional GPIO-dependent selects throughout the kernel.
