crypto: sun4i-ss - Fix 64-bit size_t warnings

BugLink: https://bugs.launchpad.net/bugs/1859712
[ Upstream commit d6e9da21ee8246b5e556b3b153401ab045adb986 ]

If you try to compile this driver on a 64-bit platform then you
will get warnings because it mixes size_t with unsigned int which
only works on 32-bit.

This patch fixes all of the warnings.
