coresight: etm3x: Prohibit modifying cntr_val while session is enabled
cntr_val are overwritten with the values read from the corresponding
registers by etm_disable_hw() when the session is disabled.
This means that any changes to this value made while the session is
enabled would be lost when the session is disabled.
Also, reset shouldn't be called while session is enabled.
Therefore, prohibit modifying cntr_val and reset while the session is
enabled.
