crypto: aegis128/simd - build 32-bit ARM for v8 architecture explicitly
Now that the Clang compiler has taken it upon itself to police the compiler command line, and reject combinations for arguments it views as incompatible, the AEGIS128 no longer builds correctly, and errors out like this: clang-10: warning: ignoring extension 'crypto' because the 'armv7-a' architecture does not support it [-Winvalid-command-line-argument] So let's switch to armv8-a instead, which matches the crypto-neon-fp-armv8 FPU profile we specify. Since neither were actually supported by GCC versions before 4.8, let's tighten the Kconfig dependencies as well so we won't run into errors when building with an ancient compiler.
