[U-Boot] [RFC PATCH 6/7] reboard: arm: Move over to generic relocation

[Simon Glass]

Switch ARM over to generic relocation - unfortunately a few boards need
to be modified to make this work. We rename the relocate_code() function
here so that the existing start.S implementations are still used for now.
The next commit does the actual switch.
