Yes the way we copy firmware into the initramfs we simply copy the top
level link and do not carry the targets at all.  Later we sensibly get
rid of hanging symlinks leaving no sign of the firmware.

I suspect we should be iterating over the link copy its components.

Bug description:
  On Skylake, the skl_dmc firmware is failing to load. From dmesg:

  [    0.728803] i915 0000:00:02.0: Direct firmware load for i915/skl_dmc_ver1.bin failed with error -2
  [    0.728817] [drm:i915_firmware_load_error_print [i915]] *ERROR* failed to load firmware i915/skl_dmc_ver1.bin (0)

  This means the GPU can't enter its lowest available power states, plus
  many display hotplugging scenarios (that only the skl_dmc firmware can
  handle) are broken.

  On a whim I tried some other firmware versions:

  1) pointed the skl_dmc_ver1.bin symlink to skl_dmc_ver1_18.bin
  (instead of skl_dmc_ver1_19.bin)

  2) downloaded the latest (skl_dmc_ver1_21.bin) and pointed the
  skl_dmc_ver1.bin symlink to it

  But neither corrected the situation.

  Thanks!
