Document the new sysfs entries triginstatus[1-3], trigoutstatus[1-3],
ittrigin[1-3], ittrigout[1-3], ittrigoutack[1-3] and ittriginack[1-3]
in the coresight-cti ABI documentation.
Also document the previously undocumented base integration test
registers itctrl, itchin, itchinack, ittrigin, ittriginack, itchout,
itchoutack, ittrigout and ittrigoutack, which were introduced in
kernel version 5.7.
