crypto: hisilicon/zip - optimize the address offset of the reg query function

Browse Source 
Currently, the reg is queried based on the fixed address offset
array. When the number of accelerator cores changes, the system
can not flexibly respond to the change.

Therefore, the reg to be queried is calculated based on the
comp or decomp core base address.
