For some layouts it is necessary to adjust the CK_DELAY parameter to
successfully complete DDR training. Add the ability to specify the
CK_DELAY in the mv_ddr_topology_map.

This patch tries to implement a generic watchdog_reset() function that
can be used by all boards that want to service the watchdog device in
U-Boot. This watchdog servicing is enabled via CONFIG_WATCHDOG.
Without this approach, new boards or platforms needed to implement a
board specific version of this functionality, mostly copy'ing the same
code over and over again into their board or platforms code base.
With this new generic function, the scattered other functions are now
removed to be replaced by the generic one. The new version also enables
the configuration of the watchdog timeout via the DT "timeout-sec"
property (if enabled via CONFIG_OF_CONTROL).
This patch also adds a new flag to the GD flags, to flag that the
watchdog is ready to use and adds the pointer to the watchdog device
to the GD. This enables us to remove the global "watchdog_dev"
variable, which was prone to cause problems because of its potentially
very early use in watchdog_reset(), even before the BSS is cleared.

Enable the hardware watchdog to guard against system lock ups when
running in the SPL or U-Boot. Stop the watchdog just before booting so
that the OS can re-enable it if needed.

MV_DDR_FREQ_SAR lets the DDR frequency be determined by hardware
strapping. This also has the side effect of running the DDR clock in
synchronous mode with the CPU core clock rather than from an independent
PLL. We've seen this improve reliability in operation across a number of
boards and temperature ranges.

This is a range of stackable network switches. The SoC is Armada-385 and
there are a number of variants with differing network port
configurations. The DP variants are intended for a harsher operating
environment so they use a different i2c mux and fit industrial-temp
parts.

The SBx81LIFKW boards connect to the internal chassis management network
via a Marvell 88e6097 L2 switch. The chassis connections are direct
serdes on ports 8 and 9 with a RGMII interface on port 10 connected to
the CPU MAC.
For debugging purposes ports 0 and 1 are also taken out to headers on
the board. Because the debug interfaces are sometimes connected to with
straight ribbon cables we need to run them at 10Mbps.
