USB: serial: ti_usb_3410_5052: do not use __uX types
__uX types should only be used for user-space interactions. Also clean up uart-config endianess handling, and drop some redundant casts. Signed-off-by: Mathieu OTHACEHE <m.othacehe@gmail.com> [ johan: amend commit message ] Signed-off-by: Johan Hovold <johan@kernel.org>
