crypto: arm/aes-ce - fix broken monolithic build

When building the arm64 kernel with both CONFIG_CRYPTO_AES_ARM64_CE_BLK=y
and CONFIG_CRYPTO_AES_ARM64_NEON_BLK=y configured, the build breaks with
the following error:

arch/arm64/crypto/aes-neon-blk.o:(.bss+0x0): multiple definition of `aes_simd_algs'
arch/arm64/crypto/aes-ce-blk.o:(.bss+0x0): first defined here

Fix this by making aes_simd_algs 'static'.
