AES_CTRL_REG is used to configure AES mode. Before configuring
any mode we need to make sure all other modes are reset or else
driver will misbehave. So mask all modes before configuring
any AES mode.

Algo self tests are failing for CTR mode with omap-aes driver,
giving the following error:

[  150.053644]       omap_aes_crypt: request size is not exact amount of AES blocks
[  150.061262] alg: skcipher: encryption failed on test 5 for ctr-aes-omap: ret=22

This is because the input length is not aligned with AES_BLOCK_SIZE.
Adding support for omap-aes driver for inputs with length not aligned
with AES_BLOCK_SIZE.

For cases where total length of an input SGs is not same as
length of the input data for encryption, omap-aes driver
crashes. This happens in the case when IPsec is trying to use
omap-aes driver.

To avoid this, we copy all the pages from the input SG list
into a contiguous buffer and prepare a single element SG list
for this buffer with length as the total bytes to crypt, which is
similar thing that is done in case of unaligned lengths.

Modify crypto drivers to use the generic SG helper since
both of them are equivalent and the one from crypto is redundant.
