core: add ce_aes_xor_block()

Adds ce_aes_xor_block() which xors two memory blocks of size
TEE_AES_BLOCK_SIZE and saves the result back into memory. The operations
are done with SIMD instructions so the memory blocks may be unaligned,
but VFP must be enabled with thread_kernel_enable_vfp().

core: add accelerated AES routines

Adds Arm CE accelerated AES routines to core/arch/arm/crypto. The code
originates from the previous implementation inside LTC library. With
this multiple crypto library can share these routines.

A new header file, <crypto/crypto_accel.h>, is added with primitive
functions implementing crypto accelerated ciphers.

The old CFG_CRYPTO_AES_ARM64_CE and CFG_CRYPTO_AES_ARM32_CE are
replaced by CFG_CRYPTO_AES_ARM_CE.

CFG_CORE_CRYPTO_AES_ACCEL is introduced as to indicate that some kind of
AES acceleration is available, not necessarily based on Arm CE.
