Fabio Estevam c280ec210f udoo: Call gpio_request()
Calling gpio_request() prior to its usage is now mandatory.

This fixes the following GPIO errors:

How to use U-Boot on MX6Q/DL Udoo boards
----------------------------------------

- Build U-Boot for MX6Q/DL Udoo boards:

$ make mrproper
$ make udoo_defconfig
$ make

This will generate the SPL image called SPL and the u-boot.img.

- Flash the SPL image into the SD card:

sudo dd if=SPL of=/dev/mmcblk0 bs=1k seek=1; sync

- Flash the u-boot.img image into the SD card:

sudo dd if=u-boot.img of=/dev/mmcblk0 bs=1k seek=69; sync

- Insert the SD card in the board, power it up and U-Boot messages should
come up.
