[FreeBSD] update todo list on Wiki-arm-Allwinner

[Yoshiro MIHIRA]

Hi, all.

Latest Crypto engine is listed on TODO list at Wiki arm Allwinner page.

However, andrew added armv8crypto(driver for the AES accelerator on ARM
CPUs).

So I would like to update and add Crypto line on [[Supported
devices/Legend] at Wiki page.
Currently YES(r308921) is only for A64.

openssl speed aes-256-cbc
"PINE64 without crypto engine"       aes-256 cbc      20817.02k
22166.74k    22629.38k    22734.17k    22754.10k
/usr/bin/openssl speed -engine cryptodev -evp aes-256-cbc
"PINE64  with crypto engine"          aes-256-cbc      88225.27k
 207383.62k   308516.25k   360612.50k   380447.40k
