[U-Boot] [PATCH] Revert "arm: mvebu: fix boot from UART when in fallback mode"

[Chris Packham]

This reverts commit e83e2b390038c9075642cb243a6292241beb8d73. This
prevents kwboot from overriding the hardware strapped boot source.

Sean,

I take it your use case was for when the default boot source doesn't
have a valid image and it falls back to UART? If that's the case I think
we need something in addition to the existing code not instead of.
