arm: mach-omap2: Remove secure certificate name printing

The signing certificate name is always 15 chars long, but need not be
null terminated. One solution is then to use printf precision modifiers
to only print this many chars ("%.15s"), but tiny printf does not support
this, so lets just drop printing the cert name for now.
