Don't populate the array speeds on the stack but instead it
static const. Makes the object code smaller by 17 bytes:

Before:
   text    data     bss     dec     hex filename
  39987   14200      64   54251    d3eb .../huawei/hinic/hinic_sriov.o

After:
   text    data     bss     dec     hex filename
  39906   14264      64   54234    d3da .../huawei/hinic/hinic_sriov.o

(gcc version 10.3.0)
