crypto: msm: Fix key length setting

Hardcoding key length to a constant value results in overwriting
command element information in the command descriptor beyond what
is allocate for the key information in the command element list.
This results in corruption of the command list in the case where
command descriptors are used for configuring crypto registers and
needlessly writing to key registers that are not relevant to the
operation (when writing to registers directly), and thus leads to
crypto operation failures. Fix is to use the key length based on
what is requested by the client.

crypto: msm: Rename and register crypto algorithms

Add optional crypto algorithm flags to indicates if to use SW crypto
algorithms instead of HW algorithms. Based on it, we then rename and
register crypto algorithms to be qualcomm specific to prevent clashing
with the default SW implementation of the algorithms used by dm_crypt
module. (used for disk encryption).

crypto: msm: Add basic suspend resume functionality

If ce clock is not disabled in suspend state, memory may be corrupted
and device can not wake up. We add an optional flag "clk_mgmt_sus_res"
for qcrypto driver. This flag indicates if the ce clocks need to be
disabled in suspend function and enabled in resume function of qcrypto
driver. When the flag is set, we disable the clocks that are not disabled
in suspend function and re-enable them again in resume function.
