Many drivers load the device's firmware image during the initialization
flow either from the flash or from the disk. Currently this option is not
controlled by the user and the driver decides from where to load the
firmware image.

'fw_load_policy' gives the ability to control this option which allows the
user to choose between different loading policies supported by the driver.

This parameter can be useful while testing and/or debugging the device. For
example, testing a firmware bug fix.

Conflicts were easy to resolve using immediate context mostly,
except the cls_u32.c one where I simply too the entire HEAD
chunk.

Devlink string param buffer is allocated at the size of
DEVLINK_PARAM_MAX_STRING_VALUE. Add helper function which makes sure
this size is not exceeded.
Renamed DEVLINK_PARAM_MAX_STRING_VALUE to
__DEVLINK_PARAM_MAX_STRING_VALUE to emphasize that it should be used by
devlink only. The driver should use the helper function instead to
verify it doesn't exceed the allowed length.

Driverinit configuration mode value is held by devlink to enable the
driver fetch the value after reload command. In case the param type is
string devlink should copy the value from driver string buffer to
devlink string buffer on devlink_param_driverinit_value_set() and
vice-versa on devlink_param_driverinit_value_get().

In case devlink param type is string, it needs to copy the string value
it got from the input to devlink_param_value.

Make sure extack is passed to nlmsg_parse where easy to do so.
Most of these are dump handlers and leveraging the extack in
the netlink_callback.
