firmware: qcom: tz_log: fix reading log issue on secure boot enabled device

Unlike other debug logs, qsee and hyp log buffer are separated from tz
diag region, so it is not necessary to read tz diag region before
reading qsee or hyp logs. Otherwise, when tz diag region is encrypted
and locked on secure boot enabled devices, reading qsee or hyp logs will
cause XPU violation at tz diag region. Also, update the diagnostic table
with some new items
