Subject: arm: pdu001: Setup pinmux for console UART as early as possible

To make sure we get a working console as soon as possible in the SPL the
UART pins require to be configured earlier. This is especially
true for the pins of UART3, since the PDU001 board uses this UART for
the console by default.
