Export the irq_chip_set_wake_parent symbol so that drivers with
hierarchical IRQ chips can be built as a module.

This fixes a build failure in linux-next's spmi-gpio when using
allmodconfig. See https://www.spinics.net/lists/linux-next/msg46362.html
for Mark's message.

Changes since v1:
- Moved message about build failure out of the commit message and into
  the notes field.
