MLK-11784 imx: mx7: uboot plugin change for mfgtool
Fixed the issue that mfgtool failed to download u-boot with plugin enabled.
The u-boot plugin common codes should not call rom___pu_irom_hwcnfg_setup
when using serial download mode.
rom___pu_irom_hwcnfg_setup will load the IVT2 image from boot media, but this
is invalid for USB serial download mode.
