Bootrom Tools: Fix number of reserved entries in tftf
Bootrom Tools: Fix number of reserved entries in tftf

When converting the TFTF tools from Python to C, discovered that the definition
of the number of reserved entries was misinterpreted. This fixes that
definition and brings the Python in-line with the C.

Testing Done: verified that the # of reserved slots went from 5 to 4
Bug Number: trivial
