arm: imx: make bmode command work with SPL/U-Boot combo
The bmode command forces the SoC to use a specific boot device
by writing its boot mode into SRC_GPR9, and notifying the SoC of
the change using SRC_GPR10[28] bit: if the bit is on, bootROM
uses the value in SRC_GPR9 instead of SRC_SMBR1 to determine
the boot device.
SPL on the other hand is oblivious to this distinction, so once
the bootROM loads SPL from the device configured in SRC_GPR10,
SPL will attempt to load U-Boot from the device configured in
SRC_SMBR1, which is not updated by the bootROM to the value in
SRC_GPR9.
The result is that the selected boot device is not used across all
the boot stages.

power_spi.c: Rewrite pmic_reg function
The pmic_spi_free function isn't ever used, and as the frameworks stand
today, cannot be, so remove it. Integrate the probe function into
pmic_reg as it's not really a "probe" today. Finally, add an err label
for the common failure cases.

image-fdt: boot_get_fdt() return value when no DTB exists
I believe that when no DTB is around we should return 1.
This why I fixed such scenarious to not return zero anymore.
Else kernel might get NULL pointer to DTB which doesn't exists.
