fsl/fman: make arrays port_ids static, reduces object code size

Browse Source 
Don't populate the arrays port_ids on the stack, instead make them static.
Makes the object code smaller by over 700 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  28785	   5832	    192	  34809	   87f9	fman.o

After:
   text	   data	    bss	    dec	    hex	filename
  27921	   5992	    192	  34105	   8539	fman.o
