Add the abstraction needed to only program the LSDIID registers for
the HDaudio extended links. It's perfectly fine to program this
register multiple times in case devices lose sync and reattach.

Select relevant ip-offset depending on hardware version. This offset
is used to access MCP_ or IP_MCP_ registers with a fixed offset.
For existing platforms, the offset is exactly zero. Starting with
LunarLake, the offset is 0x4000.

In the case where multiple peripherals are attached on the same link,
it's possible that they are in different pm_runtime states.
The device_for_each_child() loop to resume all devices before a system
suspend would not work if one peripheral was active and others
suspended. pm_runtime_resume() returns 1 in the former case, which is
taken as a error. As a result, a pm_runtime suspended device might be
skipped if the first device was active.
This patch changes the behavior of the helper function to only return
zero or a negative error. A Fixes tag is not provided since there are
no existing configurations on Intel platforms with different types of
devices on the same link. Amplifiers may be used on the same link, but
they are used by the same dailink so their pm_runtime state is always
matching. This assumption may not be true in the future, so we should
improve the behavior and align with AMD.

A previous patch removed unnecessary zeroing of the page registers
after a paged transaction, so now the reset_page_addr callback is
unused and can be removed.

The auxdevice layer is completely generic, it should be split from
intel.c which is only geared to the 'cnl' hw_ops now.
