Hello

This patch serie adds support for the Allwinner crypto engine.
The Crypto Engine is the third generation of Allwinner cryptogaphic offloader.
The first generation is the Security System already handled by the
sun4i-ss driver.
The second is named also Security System and is present on A80 and A83T
SoCs, originaly this driver supported it also, but supporting both IP bringing
too much complexity and another driver (sun8i-ss) will came for it.

For the moment, the driver support only DES3/AES in ECB/CBC mode.
Patchs for CTR/CTS/XTS, RSA and RNGs will came later.

This serie is tested with CRYPTO_MANAGER_EXTRA_TESTS
and tested on:
sun50i-a64-bananapi-m64
sun50i-a64-pine64-plus
sun50i-h5-libretech-all-h3-cc
sun50i-h6-pine-h64
sun8i-h2-plus-libretech-all-h3-cc
sun8i-h2-plus-orangepi-r1
sun8i-h2-plus-orangepi-zero
sun8i-h3-libretech-all-h3-cc
sun8i-h3-orangepi-pc
sun8i-r40-bananapi-m2-ultra

Regards

Changes since v2:
- changed additionalproperties
- splited fallbacks functions out of sun8i_ce_cipher()
- changed variant "model" to "has_t_dlen_in_bytes"
- splited sun8i_ce_register_algs/sun8i_ce_get_clks out of sun8i_ce_probe()

Changes since v1:
- Add sun4i-ss to allwinner directory
- Cleaned variant structure
- Renamed clock name from ahb to bus (and mbus to ram)
- Fixed DT bindings problem reported by mripard
- Cleaned unneeded status = ""  in R40 DT
- Removed old unnecessary interrupt_names in A64 DT
- Added arm64 defconfig
- Added support for PM functions
- Splitted probe functions
- Reworked clock settings
- made reset mandatory
