This patch fixes a few obvious bugs in DSP loader stuff:
- Fix possible memory leaks in the error path
- Avoid double-free calls in dma_reset()
- Properly set/unset WC bits for DMA buffers
- Add missing error status checks

A Haswell test machine showed that the invalid connection list, but
this time it has only a single pin on the codec, thus the former fixup
code doesn't work as it assumes the three pins blindly.

This patch splits the former fixup code to two parts:
- Enable eDP 1.2 for Haswell codec
- Fix the connection list of pins on Haswell codec;
  the converter list is recorded dynamically in hdmi_add_cvt(), and
  applied in hdmi_add_pin()

Some Haswell machines support more than one display outputs (HDMI or DP),
but its BIOS may not enable the codec's 2nd and 3rd pin and output cvt widgets.

This patch implements a board-specific fixup for Intel Haswell Machines:
If the hidden pins are not enabled by BIOS, the driver will enable them
and call common code to update the codec tree.

A codec may allow software to hide some unused pin/cvt widgets.

Sometimes BIOS does not enable the hidden widgets properly although they are
needed for the board. Thus the driver need to enable them as a board-specific
fixup and the whole tree will change.

This patch implements a common code for rereading codec widgets. So the fixup
code can call it after enabling the hidden widgets.

Currently we set the max number of connections to be 32, but there
seems codec that gives longer connection lists like AD1988, and we see
errors in proc output and else.  (Though, in the case of AD1988, it's
a list of all codecs connected to a single vendor widget, so this must
be something fishy, but it's still valid from the h/w design POV.)

This patch tries to remove this restriction.  For efficiency, we still
use the fixed size array in the parser, but takes a dynamic array when
the size is reported to be greater than that.

Now the fixed array size is found only in patch_hdmi.c, but it should
be fine, as the codec itself can't support so many pins.

Commit d45e6889 ("ALSA: hda - Provide
the proper channel mapping for generic HDMI driver") added support for
custom channel maps in the HDA HDMI driver. Due to a mistake in an
'if' condition the custom map is always used even when no such map has
been set. This causes incorrect channel mapping for multichannel audio
by default.

Pass per_pin->chmap_set to hdmi_setup_channel_mapping() as a parameter
so that it can use it for detecting if a custom map has been set instead
of checking if map is NULL (which is never the case).

For non-snoop mode, we fiddle with the page attributes of CORB/RIRB
and the position buffer, but also the ring buffers.  The problem is
that the current code blindly assumes that the buffer is contiguous.
However, the ring buffers may be SG-buffers, thus a wrong vmapped
address is passed there, leading to Oops.

This patch fixes the handling for SG-buffers.
