EDITME: cover title for arm64-sme-mode-switch-doc

The rest of the documentation needs more thorough review, but it seems
wise to remove the incorrect statement to avoid confusion.

# Describe the purpose of this series. The information you put here
# will be used by the project maintainer to make a decision whether
# your patches should be reviewed, and in what priority order. Please be
# very detailed and link to any relevant discussions or sites that the
# maintainer can review to better understand your proposed changes. If you
# only have a single patch in your series, the contents of the cover
# letter will be appended to the "under-the-cut" portion of the patch.

# Lines starting with # will be removed from the cover letter. You can
# use them to add notes or reminders to yourself. If you want to use
# markdown headers in your cover letter, start the line with ">#".

# You can add trailers to the cover letter. Any email addresses found in
# these trailers will be added to the addresses specified/generated
# during the b4 send stage. You can also run "b4 prep --auto-to-cc" to
# auto-populate the To: and Cc: trailers based on the code being
# modified.
