[U-Boot] [PATCH 24/25] sf: Add a method to obtain the block-protect setting

[sjg at google.com]

It is useful to obtain the block-protect setting of the SPI flash, so we
know whether it is fully open or (perhaps partially) write-protected. Add
a method for this. Update the sandbox driver to process this operation and
add a test.
