spi: pic32: remove unnecessary of_node_get()

Almost all spi drivers assign spi master->dev.of_node from its parent platform device without additional refcounting. It seems of_node_get() in pic32_spi_probe() is unnecessary and there is no corresponding of_node_put(). Found by Linux Driver Verification project (linuxtesting.org).
