Enable pull-up on Rx serial ports for the CALAO MB-QIL-A9260
This patch prevents to stop the autoboot randomly for the CALAO MB-QIL-A9260.
Indeed on this board, there's no pull-up on the RX inputs for the DBGU, COM1 & COM2 serial port.
With pull-up enabled, there's no longer unwanted character received from these console (CONFIG_CONSOLE_ACTIVATE_ALL=y).
