usb: phy-generic: Delete unused platform data
The last user of the phy generic platform data was deleted in commit 1e041b6f313aaa966612a7e415cfc09c90d6b829 ("usb: dwc3: exynos: Remove dead code"). So get rid of the platform data, which rids us of another consumer of the legacy GPIO API at the same time. Make sure we only inlcude <linux/gpio/consumer.h> which is all we use. Alter the usb_phy_gen_create_phy() function prototype to not pass any platform data as this is just hardcoded to NULL at all locations calling it in the kernel. Move the devm_gpiod_get* calls out of the if (of_node) parenthesis, as these calls are generic and do not depend on device tree, they are used by any hardware description.
