Fabio Estevam 946db0cbd0 mx7dsabresd: Directly write to register LDOGCTL 
Register LDOGCTL contains only bit 0 as a valid bit, so there is no need
to do a read-modify-write operation.

Simplify the code by writing directly to this register.

How to use U-Boot on Freescale MX6UL 14x14 EVK
-----------------------------------------------

- Build U-Boot for MX6UL 14x14 EVK:

$ make mrproper
$ make mx6ul_14x14_evk_defconfig
$ make

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

- Flash the SPL image into the micro SD card:

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

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

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

- Jumper settings:

SW601: 0 0 1 0
Sw602: 1 0

where 0 means bottom position and 1 means top position (from the
switch label numbers reference).

- Connect the USB cable between the EVK and the PC for the console.
(The USB console connector is the one close the push buttons)

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