This series converts all drivers for h/w accelerators that produce the
ablkcipher API to the skcipher API, so that we can finally retire the
long deprecated ablkcipher code.

Changes since v2:
- added a patch that removes the ablkcipher support code itself
- fix an issue in the talitos code
- add tero's ack to patch #5
- add stanimir's ack to patch #20

Changes since v1:
- remove some more [cosmetic] references to [a]blkcipher (#26-#27)
- add back missing IV for cbc(aes) in the omap driver, fixing a crash
- add Gary's ack to #4
- add Linus's ack to #6 and #15
- add Kamil's and Krzysztof's acks to #7
- fixed a bug in the Atmel patch (#8)
- add Horia's tested-by to #16
- add Dave's ack to #22

Patches #1, #2 are fixes for the virtio driver, which need to be applied
first so that they can be backported

Patches #3 and #4 have been tested on actual 'hardware' (given the virtual
nature of the virtio driver). Patch #7 was tested successfully in kernelci.
Patch #5 was tested by Tero. Patch #16 was tested by Horia.

All other patches have been build tested *only*, and should preferably be
tested on actual hardware before being merged. Note that patches can be
merged piecemeal (with the exception of #1 .. #3 which should be taken as a
set, and #28 which removes the ablkcipher support code) since there are no
dependencies between them. However, deferring this series indefinitely until
everyone has chimed in doesn't seem like a useful approach either, so I am
leaving it up to the maintainers to decide when we have reached critical
mass and the whole series can be taken.
