crypto: hisilicon - support get algs by the capability register

Browse Source 
The value of qm algorithm can change dynamically according to the
value of the capability register.

Add xxx_set_qm_algs() function to obtain the algs that the
hardware device supported from the capability register and set
them into usr mode attribute files.
