kernel: remove obsolete phylink/SFP patches

Remove the old phylink/SFP patches from the OpenWRT build; these will
be updated with a new set in subsequent.

450-reprobe_sfp_phy is also removed for several reasons:
1) it is not in mainline.
2) it breaks copper modules that do not have a PHY.
3) it makes backporting the current patch set harder.

Discussion is ongoing with the patch author for a mainline Linux kernel
patch for this.
