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.
