Adds device driver support for crypto and hash acceleration for the u8500 chip.
ST-Ericsson Linux next: Builds and boot, but fails on cryp probe ER320876.

crypto: ux500: cryp: Add power-awareness
Adds power awareness to the cryp part of the device driver for accelerating crypto in u8500.
ST-Ericsson ID: ER277473
crypto: ux500: cryp: Fix of NULL pointer dereference in power-save
Fix of NULL pointer dereference in cryp_disable_power.

crypto: ux500: cryp/hash: Power-awareness
- Hash:
Adds power awareness to the hash part of the device driver for accelerating
hashing in u8500.
- Cryp:
- Removed erroneous call to cryp_enable_power() in u8500_cryp_resume().
- Added spinlocks to protect usage of current_ctx.
- Corrected erroneous gotos in hw_cryp_noxts().
- Added down_interruptible()/up() in suspend/resume, to make sure
the device is not allocated during suspend.

crypto: ux500: AES ECB converted to ablk_cipher and supports DMA.
- DMA support for AES_ECB added.
- ablk_cipher support added to the driver. In this commit AES_ECB
is using this asynchronous API. This is a must since you will get
miscellaneous sleep warning- error-messages from the crypto testmgr
which runs sanity tests when loading a module in synchrounous mode
using DMA. Therefore DMA operations should use the ablk_cipher
(asynchronous) API,
- Added scatterlist walk function for ablk_cipher for the non DMA
version.
- Added power awarness to DMA related code in this cryp driver.
- Refactored code in hw_cryp_noxts with functions calls when
getting the device and when setting up the context.
- Renamed registers so they corresponds to the names in the design
spec.

ST-Ericsson Linux next: ER320876, v-ape regulator missing.
crypto: ux500: cryp: DES ECB converted to ablk_cipher.
ablk_cipher support added to the driver. In this commit DES_ECB
and DES3_ECB is using this asynchronous API.
This removes the log printout:
BUG: sleeping function called from invalid context at kernel/mutex.c:94.
ST-Ericsson ID: ER322583
crypto: ux500: cryp: More algorithms converted to use ablk_cipher.
In this commit AES_CBC, AES_CTR, DES_CBC and DES3_CBC
is using the asynchronous API.
These algorithms also support DMA, except for givciphers.

crypto: ux500: cryp: Power save redesign, to improve performance
- Enable and disable power moved to be called only at beginning and end
of algorithm calls.
- Removed compiler warnings (uninitialized variables) visible using Linux-next
compiler. Note! Those warnings not visible using default compiler in the
android forest.
