The command 'gdb_report_register_access_error' is used to silence
errors while reading registers and not reporting them to GDB.
Nevertheless, the error is printed by a LOG_ERROR() in armv8_dpm.
Change the message to LOG_DEBUG().
It will still cause the error to be propagated and eventually
printed by the caller (e.g. by the command 'reg').

cortex_m_poll_one() detects reset testing S_RESET_ST sticky bit.
If the signal comes unexpectedly, poll must return TARGET_RESET state.
On the contrary in case of polling inside of an OpenOCD reset command,
TARGET_RESET has been has already been set and we need to get out of
it as quickly as possible.
The original code needs 2 polls: the first clears S_RESET_ST
and keeps TARGET_RESET state, the current TARGET_RUNNING or TARGET_HALTED
is reflected as late as the second poll is done.
Change the logic to keep in TARGET_RESET only when necessary.

Erase is initiated by write to a flash address. Due to the
silicon errata of nRF91 the write stalls the bus until the page erase
is finished (takes up to 87ms).
If the adapter does not handle SWD WAIT properly, the following read
in nrf5_wait_for_nvmc() returns ERROR_WAIT.
Wait for fixed time before accessing AP. Not nice, but the only
working solution until all adapters handle SWD WAIT.
If the fixed wait does not suffice, continue the wait loop after a delay.
It makes some unnecessary noise however erase works.

Targets created with -defer-examine gets the examine flag reset

Commit 236c54c94a ("server/gdb_server.c: support unavailable
registers") correctly returns a string of 'x' when the register is
not available in the current target.
While implementing this, it incorrectly drops the pre-existing
feature of optionally ignoring errors while reading a register.
This feature has a real use case documented in the OpenOCD manual
in chapter 'Using GDB as a non-intrusive memory inspector', where
GDB attaches to a target without halting it. For targets that need
to be halted to read its registers, we need to hack the values of
the registers returned to GDB; either returning 'xxxx' or an error
causes GDB to drop the connection.
Re-add the check on 'gdb_report_register_access_error' to keep the
pre-existing behavior when a register error has to be ignored:
- return a string of '0';
- drop a debug message.

hide_csrs should not emit warnings on an attempt to hide non-exitents CSR.
hide_csrs funcitonality is intended to be used for scenarios when we don`t
want certain groups of registers to be available in GDB. Typically this is
needed to simplify integration with various IDE. In such scenarious it may
be impractical/unfeseable to figure out which register is present on a
target. So reporting a situation when a user wants to hide a non-existent
register creates way too much noise. This commit reduces severity of
relevant debug message to LOG_TARGET_DEBUG
