util/amdfwtool: Clarify call to fletcher32

The fletcher32 algorithm generates a sum over a range of 16-bit
WORDs.  Change the function's interface to be more generic,
accepting a more intuitive size in BYTEs.  Don't require the
caller to understand the nature of the algorithm and convert to
WORDs prior to calling.

TEST=Verify no difference in amdfw.rom for google/grunt before
     and after the patch is applied
