ipq40xx: files-4.19: Clear some DTC warnings

DTC was throwing warnings like this:
image-qcom-ipq4018-jalapeno.dtb: Warning (avoid_unnecessary_addr_size): /soc/spi@78b5000/m25p80@0: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property
image-qcom-ipq4018-jalapeno.dtb: Warning (avoid_unnecessary_addr_size): /soc/spi@78b5000/spi-nand@1: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property

So lets fix this for our downstream boards.
