Joel Stanley 3045d61c1c aspeed/spl: Remove OVERLAY from linker script
The generic arm linker script contains this section:

   .bss __rel_dyn_start (OVERLAY) : {
       ...
   }

The (OVERLAY) syntax in the description causes the .bss section to be
included in the NOR area of the image:

 $ objdump -t -j .bss spl/u-boot-spl
  SYMBOL TABLE:
  0000c61c l    d  .bss	00000000 .bss
  0000c640 l     O .bss	00000040 __value.0
  0000c68c g     O .bss	00000000 __bss_end
  0000c61c g     O .bss	00000000 __bss_start
  0000c680 g     O .bss	0000000c stdio_devices

This is what the custom linker script tries to avoid, as the NOR area is
read-only.

Remove the OVERLAY syntax to fix the BSS location:

 $ objdump -t -j .bss spl/u-boot-spl
  SYMBOL TABLE:
  83000000 l    d  .bss	00000000 .bss
  83000000 l     O .bss	00000040 __value.0
  0000c61c g     O .bss	00000000 __image_copy_end
  8300004c g     O .bss	00000000 __bss_end
  83000000 g     O .bss	00000000 __bss_start
  83000040 g     O .bss	0000000c stdio_devices

This restores the state of the linker script before the patch that fixed
the linker lists issue.
