[U-Boot] [PATCH v2] board/BuR/kwb: switch to board HW-Rev3

[Hannes Petermaier <oe5hpm@oevsv.at>]

The board has been redesigned, therefore we need from now other I/O Pins to
mux and handle.

Older boards aren't supported from now anymore.

Signed-off-by: Hannes Petermaier <oe5hpm@oevsv.at>

Changes for V2: None
