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. Without checking in
datasheet, assume device has only one SPI NOR flash, so code was
duplicated.
Fixes 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)
