Don't populate the arrays port_map and sl_map on the stack but
instead make them static. Makes the object code smaller by 64 bytes.

Before:
   text    data     bss     dec     hex filename
  49575    6872      64   56511    dcbf hisilicon/hns/hns_dsaf_main.o

After:
   text    data     bss     dec     hex filename
  49350    7032      64   56446    dc7e hisilicon/hns/hns_dsaf_main.o

(gcc version 9.2.1, amd64)
