Some system control registers need to be clocked, so the registers can
be accessed. Add an optional clock and attach it to regmap.

Fix multiple bugs in the OFB implementation:
1. It stored the per-request state 'cnt' in the tfm context, which can be
used by multiple threads concurrently (e.g. via AF_ALG).
2. It didn't support messages not a multiple of the block cipher size,
despite being a stream cipher.
3. It didn't set cra_blocksize to 1 to indicate it is a stream cipher.
To fix these, set the 'chunksize' property to the cipher block size to
guarantee that when walking through the scatterlist, a partial block can
only occur at the end. Then change the implementation to XOR a block at
a time at first, then XOR the partial block at the end if needed. This
is the same way CTR and CFB are implemented. As a bonus, this also
improves performance in most cases over the current approach.

The recently added helper routine to perform key strength validation
of triple DES keys is slightly inadequate, since it comes in two versions,
neither of which are highly useful for anything other than skciphers (and
many drivers still use the older blkcipher interfaces).
So let's add a new helper and, considering that this is a helper function
that is only intended to be used by crypto code itself, put it in a new
des.h header under crypto/internal.
While at it, implement a similar helper for single DES, so that we can
start replacing the pattern of calling des_ekey() into a temp buffer
that occurs in many drivers in drivers/crypto.

According to the description of the I2C_RESET(0x9E) register in
the husb311 datasheet, the main configuration is enable/disable
i2c timeout reset function(bit[7]) and i2c timeout time(bit[3:0]).
If the i2c timeout reset function is enabled, the husb311 will perform
a soft reset in some cases, such as system hibernation, and close the
i2c bus (SCL and SDA are low at the same time). So we disable the i2c
timeout reset function.
