Enable vboot for sandbox and improve debugging/format strings

Some functions of vboot are disabled for sandbox because sandbox could not
support them. This has changed, so remove the sandbox #ifdefs in the code.

Some printf() strings cause warnings on sandbox - mostly that uin64_t is
not 'long long' on a 64-bit machine. The existing format strings in U-Boot
do not seem to take account of this, so add casts to remove the warnings.

Also add a few more debug strings to make it easier to see what is happening
in the vboot flow.

crosfw -b sandbox -V

See there are no warnings.
