crypto: arm64/aes-blk - honour iv_out requirement in CBC and CTR modes

Update the ARMv8 Crypto Extensions and the plain NEON AES implementations
in CBC and CTR modes to return the next IV back to the skcipher API client.
This is necessary for chaining to work correctly.

Note that for CTR, this is only done if the request is a round multiple of
the block size, since otherwise, chaining is impossible anyway.

	 Say Y or M if you want to add support for I2S driver for
	 Synopsys desigwnware I2S device. The device supports upto
	 maximum of 8 channels each for play and record.

config SND_DESIGNWARE_PCM

	depends on SND_DESIGNWARE_I2S
	help
	 Say Y, M or N if you want to add a custom ALSA extension that registers
	 a PCM and uses PIO to transfer data.

	 This functionality is specially suited for I2S devices that don't have
	 DMA support.
