Changes since v1:
	- Moved code to drivers/crypto.
	- Fixed few other nits.

Changes since v2:
	- Added falling back to software sha256 in case length exceeds buffer limit.
	- Reduced one tab at lines 533, 559 and 571 in this patch.
	- Removed space after a cast at line 506 in this patch.
	- Removed blank line at line 561 in this patch.
	- Removed space before semicolon at line 576 in this patch.

Changes since v3:
	- Removed buffer limit since there are 2 regs for address hash_msg_size_high and low.
	  That means buffer length could go upto 2^64 bits which is practically
	- Removed falling back to software sha256 because there is no buffer limit.
	- Removed "/ 4" to sha1 and sha256 lengths and added increment to 4 in for
	  loop at line 573.
	- Timed out still kept to be 100 ms since this is enough for hardware to switch
	  status to idle from busy.
	  In case it couldn't that means h/w is faulty.

Changes since v4:
	- Added include for clk.h.
	- Added define for MAX_FREQ.
	- Added timeout calculation as per frequency.
	- Changed "i+=4" to "i++" and "len" to "len/4" in for loop at line 591 in this patch.
	- Added two new functions ace_sha256 and ace_sha1.

Changes since v5:
	- Removed ace_sha.h.
	- Renamed ace_sfr.h as ace_sha.h.
	- Removed timeout and checking for PRNG_ERROR bit in HASH_STATUS register.
	  PRNG_ERROR bit high means setup was not done properly. Since there is no
	  way to detect faulty h/w, we consider the possible fact that h/w should
	  not be able to setup feed properly if it's faulty.
	- Renamed function name ace_sha256 to hw_sha256 and ace_sha1 to hw_sha1.

Changes since v6:
	- Added "Acked-by: Simon Glass <sjg@chromium.org>".

Changes since v7:
	- Moved ace_sha.h to drivers/crypto.
	- Removed parantheses where not required in ace_sha.h.
	- Removed leftover time limit comment in ace_sha.c.
	- Replaced "break" with "return -EBUSY" in PRNGERROR check.
