sandbox: Add 64-bit sandbox
To debug device tree issues involving 32- and 64-bit platforms, it is useful to
have a generic 64-bit platform available.
Add a version of the sandbox that uses 64-bit integers for its physical
addresses as well as a modified device tree.

Added CONFIG_SYS_TEXT_BASE to configs/sandbox64_defconfig
