mlxsw: spectrum: Load firmware version based on devlink parameter
Load firmware version based on 'fw_load_policy' devlink parameter. The
driver supports these two options:
* DEVLINK_PARAM_FW_LOAD_POLICY_VALUE_DRIVER (0)
Default, load firmware version preferred by the driver
* DEVLINK_PARAM_FW_LOAD_POLICY_VALUE_FLASH (1)
Load firmware currently stored in flash
The second option, 'flash', allow the device to run with different firmware
version than preferred by the driver for testing and/or debugging purposes.
For example, testing a firmware bug fix.
