[meta-xilinx] [PATCH] u-boot-spl-zynq-init.inc: Fix parallellism issue

[Niko Mauno]

A race issue can be induced by do_zynq_platform_init() being fired
before do_unpack(), resulting in

  | DEBUG: Executing shell function do_zynq_platform_init
  | cp: cannot create regular file '.../git/board/xilinx/zynq/': No such file or directory
  | WARNING: exit code 1 from a shell command.

Mitigate issue by adding dependency to completion of do_unpack task
for custom do_zynq_platform_init task. Also update comment on previous
line to match the actions on next.
