coresight: etm4x: prohibit modifying cntr_val while session is enabled
cntr_val is overwritten with the values read from the corresponding
registers by etm4_disable_hw() when the session is disabled.
This means that any changes to these values made while the session is
enabled would be lost when the session is disabled.
Therefore, prohibit modifying cntr_val while the session is enabled.
