phy: rockchip: inno-usb3: debugfs creation based on CONFIG_DEBUG_FS

Browse Source 
It can avoid potential build warn/error when CONFIG_DEBUG_FS
is not set. And also fix the following warning:

drivers/phy/rockchip/phy-rockchip-inno-usb3.c:297:5: warning: no previous prototype for ‘rockchip_u3phy_debugfs_init’ [-Wmissing-prototypes]
