cli_classic: Add convenient '--{flash,get}-size' cli opt

Browse Source 
We have this in the ChromiumOS fork of flashrom which we rely
on to obtain the current flash chip in use. This ports it for
upstream consumption.

V.2: Constrain number_of_operations to one as per Nico's comment.
V.3: Rename '--get-size' to '--flash-size' however keep old arg as
     'undocumented' for back-compat.
V.4: Add missing --help line.
V.5: Add man page entry.
V.6: Use printf() directly.
