[PATCH] coresight: fix stale and misspelled kernel-doc member names

[Amit Patole <amit.patole@gmail.com>]

Several kernel-doc comments in the CoreSight headers have drifted from
the structures they describe, which makes scripts/kernel-doc warn.
Update them to match the code:

- coresight-cti.h: @nt_trig_con is a typo for nr_trig_con.

- coresight-etm.h: @use_cpu14 is a typo for use_cp14, and @base was
  replaced by @csa in commit a1b0e77ce517 ("coresight: etm3x: Convert
  raw base pointer to struct coresight access").

- coresight-etm4x.h: @bb_ctrl is not described, and @ss_status was
  moved out of struct etmv4_config into struct etmv4_drvdata (where it
  is already documented) in commit b5022acaee3b ("coresight: etm4x:
  exclude ss_status from drvdata->config"). For struct etmv4_drvdata,
  the comment names the wrong structure (etm4_drvdata), and @mode was
  moved to struct coresight_device in commit 9cae77cf23e3 ("coresight:
  Move mode to struct coresight_device").

- coresight-priv.h: the comment names struct cs_buffer instead of
  struct cs_buffers.

This reduces the kernel-doc warnings in these four headers from 13 to 3.

The struct etm4_save_state comment is intentionally left alone:
correcting its name makes kernel-doc parse it and report its ~37
undocumented register fields, which is better handled separately.

The warnings were found by running scripts/kernel-doc over the tree.
An AI coding assistant (Claude Opus 5.5) was used to locate the
warnings and draft this change; it was verified with scripts/kernel-doc
and checkpatch. No functional change.

Comment-only change. Not build-tested on arm64 (no arm64 toolchain
available); every changed line is inside a kernel-doc comment.
