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.

All platform related codes (rcar[23].c and rza{2}.c) has its own
.get_id function as "USBHS_GADGET". So, we can use a common
function for it.

According to Documentation/timers/timers-howto.txt, a driver should
use usleep_range() instead of udelay() on NON-ATOMIC CONTEXT if
"SLEEPING FOR ~USECS OR SMALL MSECS ( 10us - 20ms)".
Since the .hardware_init() and .power_ctrl() will run on NON-ATOMIC
CONTEXT, this patch replaces udelay() with usleep_range().
