usb: renesas_usbhs: Use renesas_usbhs_platform_info on of_device_id.data
In device tree environment, the previous code allocates renesas_usbhs_platform_info by using devm_kzalloc() and then copies usbhs_of_data to the allocated memory. This reason is some values (e.g. .platform_callback.get_vbus) are overwritten by the driver, but the of_device_id.data is "const". Now the driver doesn't have such a code, so this patch uses renesas_usbhs_platform_info on of_device_id.data. Note that the previous code set the pdev->dev.platform_data pointer even if device tree environment, but the value is not used. So, this patch also remove such a code.
