[U-Boot] [PATCH] common: Fix source command on 64-bit architectures

[Thierry Reding <thierry.reding@gmail.com>]

From: Thierry Reding <treding@nvidia.com>

The source command uses an unsigned long to iterate over the 32-bit
lengths array contained in the legacy image format. On architectures
where unsigned long is 64-bit this fails to find the correct entry
point of a script.
