Subject: [PATCH] PCI: qcom: Drop unused post-init callbacks

Drop the unused post_init and post_deinit callbacks that were added for
the now removed pipe clock handling.

Signed-off-by: Johan Hovold <johan+linaro@...nel.org>
---

Now that Bjorn has merged the pipe clock series:

	https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git/log/?h=pci/ctrl/qcom

the post_init and post_deinit callbacks can also be removed.

Note that this one depends on the patch adding support for modular
builds:

	https://lore.kernel.org/all/20220519094646.23009-1-johan+linaro@kernel.org/

which has been reviewed by Rob and should be ready to be picked up.

Johan
