Fabio Estevam 21f77b77af wandboard: Fix the DM_PMIC conversion
Commit ec837c82d7 ("imx6: wandboard: convert to DM_PMIC")
caused the following pmic_get() error:

CPU:   Freescale i.MX6QP rev1.0 at 792 MHz
Reset cause: POR
DRAM:  2 GiB
PMIC:  pmic_get() ret -19
...

and since the PMIC presence is used to determine the board D1 revision,
the following error is seen when booting a board rev D1:

WARNING: Could not determine dtb to use

and the kernel does not boot at all.

Fix the regression by passing "pfuze100@8" as the correct parameter
to the pmic_get() function in the DM case.

U-Boot for Wandboard
--------------------

This file contains information for the port of U-Boot to the Wandboard.

Wandboard is a development board that has three variants based on the following
SoCs: mx6 quad, mx6 quad plus, mx6 dual lite and mx6 solo.

For more details about Wandboard, please refer to:
http://www.wandboard.org/

Building U-Boot for Wandboard
-----------------------------

To build U-Boot for the Wandboard:

$ make wandboard_config
$ make

Flashing U-Boot into the SD card
--------------------------------

- After the 'make' command completes, the generated 'SPL' binary must be
flashed into the SD card;

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

(Note - the SD card node may vary, so adjust this as needed).

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

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

- Insert the SD card into the slot located in the bottom of the board (same side
as the mx6 processor)

- Connect the serial cable to the host PC

- Power up the board and U-Boot messages will appear in the serial console.
