fix(lf): fix orphaned .phyiram sections

There are  orphaned .phyiram sections from components/esp_phy/lib/esp32/libphy.a when ESP_WIFI_SLP_IRAM_OPT
is not set on esp32. It can be seen in the wifi_station example examples/wifi/getting_started/station with
the default configuration. Even though they seem to be correctly placed in flash(linker got it right), I
believe this should be fixed. At least for the esp-idf-size, because these doesn't seem to be accounted.
