Move the fixup helper functions in patch_realtek.c to hda_auto_parser.c

Some power-saving states have been left unchanged in
snd_hda_codec_reset(), and this is a potential danger because the
function may be called in various situations including the continuous
operation after that call.

This is a fix for the problem in commit 785f857d1c, the pop noise
issue on some machines with ALC269. The problem was the uninitialized
state after the resume due to the delayed resume of the codec chips.
In that commit, we tried to fix by forcibly putting the codec to D3 at
suspend. But, this still also leaves the uninitialized state after
resume, and it _might_ be still problematic with some BIOS. Since the
commit turned out to regress another issues, we reverted it in the
end.
Now, in this fix, try to fix by turning on the codec immediately at
the resume path. We need to take care of the power-saving in this
case. When the device is woken up at the power-saved state, it should
go power-saving again after the resume.

The mxs pinctrl driver will only support DT probe. That said, the mxs
device drivers can only get pinctrl state from pinctrl subsystem when
the drivers get probed from device tree.
Before converting the whole mxs platform support over to device tree,
we need to enable pinctrl dummy states for those non-DT board files
to ensure the pinctrl API adopted by mxs device drivers will work for
both DT and non-DT probe.
Instead of calling pinctrl_provide_dummies() directly in every board
file, the patch introduces soc specific calls mx23_soc_init() and
mx28_soc_init() for boards' .init_machine hook to invoke, so that
any soc specific setup for non-DT boot only can be added there.

- Get back the line separating the overheads from the disassembly, requested by
Peter Zijlstra, Linus agreed now that it is a solid line and more column real
state was harvested. Also it has the jump->arrow lines separated from it by
the address/jump target column.
- Don't change asm line color when toggling source code view. Requested by
Peter Zijlstra.

The H_REGISTER_VPA hcall implementation in HV Power KVM needs to pin some
guest memory pages into host memory so that they can be safely accessed
from usermode. It does this used get_user_pages_fast(). When the VPA is
unregistered, or the VCPUs are cleaned up, these pages are released using
put_page().
However, the get_user_pages() is invoked on the specific memory are of the
VPA which could lie within hugepages. In case the pinned page is huge,
we explicitly find the head page of the compound page before calling
put_page() on it.
At least with the latest kernel, this is not correct. put_page() already
handles finding the correct head page of a compound, and also deals with
various counts on the individual tail page which are important for
transparent huge pages. We don't support transparent hugepages on Power,
but even so, bypassing this count maintenance can lead (when the VM ends)
to a hugepage being released back to the pool with a non-zero mapcount on
one of the tail pages. This can then lead to a bad_page() when the page
is released from the hugepage pool.
This removes the explicit compound_head() call to correct this bug.

This reverts commit 785f857d1c.
The commit causes a problem with the wrong D3 state after suspend
because the call of hda_set_power_state() involves with the power-up
sequence, which changes the power_count, and this confuses the resume
sequence that checks the power_count as well.
Originally, this go-to-D3 sequence should be a simple task without the
power-up sequence. But, it'd need some proper sanity checks in the
case of power-saved state, so it's not too easy to write now in the
3.4-rc cycle.
In short, the safest option now is to revert this affecting commit.
Of course, we need to clean up and robustify the power-saving code
better for 3.5 kernel.
