cr50: add rollback information to the sysinfo command output
With enabling INFO1 map based rollback protection it is important to
be able to tell the state of the flash map and the currently installed
images' infomap header field.
The new function counts number of zero words in the info map and zero
bits in both RW headers, and returns them in a string printed out by
the sysinfo command.
BRANCH=cr50
BUG=b:35774863
TEST=built images with different manifest info field contents and
verified that the string printed by the sysinfo command makes sense.
