Setting a global variable in per-device routine is quite bad design.

There is a reason for that we don't want to change the exist 
lpuart32_read[write] API which is widely used in driver.
Making a global lpuart_is_be is the simplest way to do it.

Any strong blocking reason?

Code should be consistent.

There is no good reason to have sport->lpuart32 inside sport, but
lpuart_is_be outside of it. Both these values describe properties of
particular device, and thus should be in per-device structure.

If that implies adding sport arg to lpuart32_(read|write), just do that.
