Now the driver fixes the issue of the commit 482982062f ("usb:
gadget: renesas_usbhs: bugfix: don't modify platform data") by
using usbhs_mod_info.get_vbus, this patches uses the pointer
instead of copied value to avoid redundancy. Note that struct
renesas_usbhs_driver_param has to use copied value because
the driver has to set some members (e.g. buswait_bwait).

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.

This is done on a quest to remove the 700+ different ways that files in

like the address (sometimes incorrect) for the FSF which is never
