Krzysztof Kozlowski 6c7c4b91aa arm64: dts: microchip: sparx5_pcb135: drop duplicated NOR flash 
Since beginning the DTS extended the SPI0 in two places adding two SPI
muxes, each with same SPI NOR flash.  Both used exactly the same
chip-selects, so this was clearly buggy code.  Then in commit
d0f482bb06 ("arm64: dts: sparx5: Add the Sparx5 switch node") one SPI
mux was removed, while keeping the SPI NOR flash node.

This still leaves duplicated SPI nodes under same chip select 0,
reported by dtc W=1 warnings:

  sparx5_pcb135_board.dtsi:92.10-96.4: Warning (unique_unit_address_if_enabled): /axi@600000000/spi@600104000/flash@0: duplicate unit-address (also used in node /axi@600000000/spi@600104000/spi@0)

Steen Hegelund confirmed that in fact there is a SPI mux, thus remove
the duplicated node without the mux.
