usb: renesas_usbhs: fix __le16 warnings 

Fix the warnings generated by casting to/from __le16 without
using the correct functions.

Fixes the following sparse warnings:

drivers/usb/renesas_usbhs/common.c:165:25: warning: incorrect type in assignment (different base types)
drivers/usb/renesas_usbhs/common.c:165:25:    expected restricted __le16 [usertype] wValue

drivers/usb/renesas_usbhs/common.c:175:39:    expected unsigned short [usertype] data

Note. I belive this to be correct, and should be a no-op on arm.
