Markus Hubig	7d899c14cc	Fixes the crippled console output on PortuxG20. In order to use the serial interface on the PortuxG20 we need to enable the level converter first by setting the PC9 pin to high. The level converter needs some time to settle so we have to use the mdelay() function to wait for some time. Unfortunately we have no timers available at board_early_init_f() so we enable the serial output early within board_postclk_init().

Fixes the crippled console output on PortuxG20.

In order to use the serial interface on the PortuxG20 we need to enable the
level converter first by setting the PC9 pin to high. The level converter needs
some time to settle so we have to use the mdelay() function to wait for some
time. Unfortunately we have no timers available at board_early_init_f() so we
enable the serial output early within board_postclk_init().

Now the U-Boot output looks fine:
