Commit "gpiolib: request the gpio before querying its
direction" (108d23e322a247d9f89ba2e2742520ead0944cc9) is causing a
regression on Marvell platforms, and potentially other platforms as
well. With this commit applied, we lose the serial console. Reverting
this commit makes the serial console functional again.

I have reverted this patch for now.
