Use ModExp fast mode for Miller-Rabin tests.
Trying to make RSA key generation run in constant time is probably
both futile and unnecessary, so we can speed it up a bit by switching
the ModExpA7 core to use "fast" mode rather than "constant time" mode.
Sadly, while this change produces a measureable improvement, it
doesn't bring FGPA ModExp anywhere near the speed of the software
equivalent in this case. Don't really know why.
