target/cortex_m: supress historical reset detection

The S_RESET_ST sticky bit is reset after DHCSR read.
It is set at power-on reset and keeps active until the debuger reads DHCSR.

Ignore S_RESET_ST at the very first read after OpenOCD start
and suppress possibly misleading message "external reset detected"
if we cannot guarantee the reset happened recently.

While on it add a TODO comment.
