At present all the 'command' methods return bytes. Most of the time we
actually want strings, so change this. We still need to keep the internal
representation as bytes since otherwise unicode strings might break over
a read() boundary (e.g. 4KB), causing errors. But we can convert the end
result to strings.

Add a 'binary' parameter to cover the few cases where bytes are needed.

This board appears to be very near its size limit and cannot accept the
new checking code in libfdt. Disable this code so this the board can
continue to build.

For better or worse libfdt recent grew a lot of code that checks the
validity of the device tree in great detail. When using unsigned or
unverified data this makes things safer, but it does add to code size.

Add some controls to select the trade-off between safety and code size.

Unfortunately libfdt needs this value now, which is present in the
stdint.h header. That file is just a placeholder in U-Boot and these sorts
of constants appear in the linux/kernel.h header instead.

To keep libfdt happy, add INT32_MAX too.
