[U-Boot] [PATCH v2 02/17] sandbox: Unprotect DATA regions in bus tests

[sjg at google.com]

On my Ubuntu 18.04.1 machine two driver-model bus tests have started
failing recently. The problem appears to be that the DATA region of the
executable is protected. This does not seem correct, but perhaps there
is a reason.

To work around it, unprotect the regions in these tests before accessing
them.
