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. Update spl_boot_device() to look at gpr9 when necessary.
