mlxsw: core: Set thermal zone polling delay argument to real value at init

Thermal polling delay argument for modules and gearboxes thermal zones
used to be initialized with zero value, while actual delay was used to
be set by mlxsw_thermal_set_mode() by thermal operation callback
set_mode(). After operations set_mode()/get_mode() have been removed by
cited commits, modules and gearboxes thermal zones always have polling
time set to zero and do not perform temperature monitoring.

Set non-zero "polling_delay" in thermal_zone_device_register() routine,
thus, the relevant thermal zones will perform thermal monitoring.
