Subject: net: hns3: make array spec_opcode static const, makes object smaller
Patch-mainline: v5.4-rc1
Git-commit: e9ac25b70da4003fdcc95ecfb9bacce19ede03db
References: bsc#1154353

Don't populate the array spec_opcode on the stack but instead make it
static const. Makes the object code smaller by 48 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
   6914	   1040	    128	   8082	   1f92	hns3/hns3vf/hclgevf_cmd.o

After:
   text	   data	    bss	    dec	    hex	filename
   6866	   1040	    128	   8034	   1f62	hns3/hns3vf/hclgevf_cmd.o

(gcc version 9.2.1, amd64)
