Add support for MD5, SHA1, SHA256 hash algorithms for Exynos HW.
It uses the crypto framework asynchronous hash api.
It is based on omap-sham.c driver.
S5P has some HW differencies and is not implemented.

Modifications in s5p-sss:

- Add hash supporting structures and functions.

- Modify irq handler to handle both aes and hash signals.

- Resize resource end in probe if EXYNOS_HASH is enabled in
  Kconfig.

- Add new copyright line and new author.

- Tested on Odroid-U3 with Exynos 4412 CPU, kernel 4.13-rc6
  with crypto run-time self test testmgr
  and with tcrypt module with: modprobe tcrypt sec=1 mode=N
  where N=402, 403, 404 (MD5, SHA1, SHA256).

Modifications in drivers/crypto/Kconfig:

- Add new CRYPTO_DEV_EXYNOS_HASH, depend on !EXYNOS_RNG
  and CRYPTO_DEV_S5P

- Select sw algorithms MD5, SHA1 and SHA256 in EXYNOS_HASH
  as they are needed for fallback.

All defconfigs selecting the old driver have been patched to select
the new one instead. We can now remove the old driver along with the
allhwsupports module parameter in the new driver that was used to
check whether the new driver was allowed to take control of the CESA
engine or not.

This is an asynchronous crypto API driver for the accelerator present
in the ARTPEC-6 and -7 SoCs from Axis Communications AB.

The driver supports AES in ECB/CTR/CBC/XTS/GCM modes and SHA1/2 hash
standards.

The CCP device is part of the AMD Secure Processor. In order to expand
the usage of the AMD Secure Processor, create a framework that allows
functional components of the AMD Secure Processor to be initialized and
handled appropriately.

Add ECDH support for ATECC508A (I2C) device.

The device features hardware acceleration for the NIST standard
P256 prime curve and supports the complete key life cycle from
private key generation to ECDH key agreement.

Random private key generation is supported internally within
the device to ensure that the private key can never be known
outside of the device. If the user wants to use its own private
keys, the driver will fallback to the ecdh software implementation.

SPU driver is dependent on generic MAILBOX API's to
communicate with underlying DMA engine driver.

So this patch removes BCM_PDC_MBOX "depends on" for SPU driver
in Kconfig and adds MAILBOX as dependent module.

The s390_paes and the s390_aes kernel module used just one
config symbol CONFIG_CRYPTO_AES. As paes has a dependency
to PKEY and this requires ZCRYPT the aes module also had
a dependency to the zcrypt device driver which is not true.
Fixed by introducing a new config symbol CONFIG_CRYPTO_PAES
which has dependencies to PKEY and ZCRYPT. Removed the
dependency for the aes module to ZCRYPT.
