3408399172 sma: added tweak mode in sma crypto
AES-XTS requires providing tweak. By definition tweak (128bits)
represents logical position of the data being encrypted or decrypted,
typically for nvme it is LBA.
Various implementations of AES-XTS can treat that requirment
in different way, because AES-XTS specification doesn't define
how exactly tweak look like and how exactly LBA is transformed
into tweak  For example:
 - Tweak[127:0] = {1’b0, ~LBA[62:0], LBA[63:0]}
 - Tweak[127:0] = {LBA[127:0] + 1}
 - Tweak[127:0] = {LBA[63:0] + 1, 64'b0}

So there's a need of specifying mode of tweak

cc3f842cd1 sma: initial crypto definitions
This patch defines the interface for crypto engines, which provide
support for configuring crypto on a given volume.  Only a single crypto
engine can be active at a time and it's selected in the "crypto" section
of the config file.  Similarly to device managers, external crypto
engines can be loaded from plugins.
