[v2,0/7] crypto: sun4i-ss: prevent always fallback for ciphers

Hello

For help testing on "crypto: sun4i-ss - Fix sparse endianness markers",
I have added "stats" support like other allwinner's crypto drivers.
Seeing stats showed a clear problem, the ciphers function were not used
at all.
This is due to the not-inialized need_fallback which is "init" as true
everytime.
So basicly, since the patch introduced it, this probem hidden some bugs.

This serie fixes all hidden problems, then fix the initialization of
"need_fallback" and then add the stats like other allwinner drivers.

Regards

Changes since v1:
- patch #4 is sufficient to fix BE problem (removed todo)
