Add wrs_auxclk to start at boot

NOTE: This branch requires new Gateware! wrs_auxclk will hang switch when using
      gateware from last release of switch.

Added init script /etc/init.d/S70wrs_auxclk to start wrs_auxclk with parameters
read from dot-config.

Added parameters to Kconfig:
--WRSAUXCLK_FREQ
--WRSAUXCLK_DUTY
--WRSAUXCLK_CSHIFT
--WRSAUXCLK_SIGDEL
--WRSAUXCLK_PPSHIFT
All above are used as parameters to wrs_auxclk,
which configure external clock clk2

NOTE: This patch requires new Gateware! wrs_auxclk will hang switch when using
gateware from last release of switch.

Introduce saving time before restart, which is restored after restart.
Aslo report date of last firmware update.

Add reporting of when last update of switch firmware took place via SNMP.
If update date is not known return "0000.00.00-00:00:00"

Note: Be aware that date of last update may be not accurate.
One reason is that it uses date stored before last restart, so time needed to restart is not taken into account.
Additionally date stored before restart may be not accurate for many reasons like:
--hard restart (last know date was not saved)
--date was never received from ntp nor set manually

This patch is to replace previous way of managing ppsi configuration file.
Instead of copying proper file based on chosen configuration PTP_* option in
dot-config, now ppsi.conf file is assembled based on PORTXX_PARAMS fields in
dot-config.

--Kconfig:
  - remove options:
    - PTP_WR_DEFAULT
    - PTP_WR_MASTER
    - PTP_WR_AUTO
    - PTP_WR_AUTO_UDP
    - PTP_NONWR_UDP_ALL
  - add PTP_PORT_PARAMS (to let assembly ppsi.conf file)
  - keep option PTP_CUSTOM to use user's ppsi configuration file
  - move PTP_CUSTOM_FILENAME to different position
  - add property "proto" to PORTXX_PARAMS
--remove predefined ppsi configs (not to be used anymore) from /wr/etc/ppsi-config-pool/:
    - WR_DEFAULT
    - WR_MASTER
    - WR_AUTO
    - WR_AUTO_UDP
    - NONWR_UDP_ALL
--add new script assembly_ppsi_conf.sh to create ppsi.conf file.
  ppsi.conf file is assembled based on PORTXX_PARAMS fields like port name,
  proto(col) and role. All master, slave or auto ports are set to use whiterabbit
  extension
--add file /wr/etc/ppsi-pre.conf to keep top of ppsi.conf including global
  options (later all options may be moved to dot-conf)
--modivy apply_dot-config to use assembly_ppsi_conf.sh instead of old way.

While checking return status first WIFEXITED has to be checked to know if child
returned normally.
waitpid's man page:
WEXITSTATUS(status) returns the exit status of the child. (...) This macro
should be employed only if WIFEXITED returned true.
WIFEXITED(status) returns true if the child terminated normally, that is, by
calling exit(3) or _exit(2), or by returning from main().
