stm32_min_dev board no console output

[explora26]

I'm trying to test hello world example with stm32_min_dev board, but the UART didn't output anything.

I found that the last workable commit SHA is 9612f9d, maybe this issue cause by 2fb616e

@explora26 , if you have access to gdb, can you do the following before and after the change?

(gdb)x /4x 0x40010800
0x40010800:	0x44444944	0x88844444	0x0000dfdc	0x0000a000

Here is the registers dump:
Before revert 2fb616e :

(gdb)x /4x 0x40010800
0x40010800:	0x44444444	0x88844444	0x0000dfff	0x0000a000

After revet 2fb616e :

(gdb)x /4x 0x40010800
0x40010800:	0x44444444	0x88844494	0x0000dfff	0x0000a000

Looks like the port configuration register incorrect.

@explora26, great txs! This piece of code was indeed my suspect number 1, but I couldn't spot the issue.
Would you push a PR to fix it?
