ASoC: Updates for v6.17

There's a few new drivers here and quite a lot of cleanup work from
Morimoto-san but generally this has been quite a quiet release,
resulting in a fairly small diffstat. Highlights include:

- Refactoring of the Kconfig menus to be hopefully more consistant and
easier to navigate.
- Refactoring of the DAPM code, mainly hiding functionality that
doesn't need to be exposed to drivers.
- Removal of the unused upstream weak paths DAPM functionality.
- Further work on the generic handling for SoundWire SDCA devices.
- Cleanups of our usage of the PM autosuspend functions, this pulls in
some PM core changes on a shared tag.
- Support for AMD ACP7.2 and SoundWire on ACP 7.1, Fairphone 4 & 5,
various Intel systems, Qualcomm QCS8275, Richtek RTQ9124 and TI TAS5753.

nfs: Clean up /proc/net/rpc/nfs when nfs_fs_proc_net_init() fails.

syzbot reported a warning below [1] following a fault injection in
nfs_fs_proc_net_init(). [0]

When nfs_fs_proc_net_init() fails, /proc/net/rpc/nfs is not removed.

Later, rpc_proc_exit() tries to remove /proc/net/rpc, and the warning
is logged as the directory is not empty.

Let's handle the error of nfs_fs_proc_net_init() properly.
