bcma: make arrays pwr_info_offset and sprom_sizes static const, shrinks object size 

Arrays pwr_info_offset and sprom_sizes can be make static const rather
than populating them on the stack. Shrinks object size by 236 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  11300	   1320	     64	  12684	   318c	drivers/bcma/sprom.o

After:
   text	   data	    bss	    dec	    hex	filename
  10904	   1480	     64	  12448	   30a0	drivers/bcma/sprom.o

(gcc version 9.2.1, amd64)
