1e2872f591 spi: dt-bindings: nuvoton,wpcm450-fiu: Fix error in example (bogus include) 
The nuvoton,wpcm450-fiu binding's example includes
nuvoton,wpcm450-clk.h, which has not been merged yet,
thus causing a dt_binding_check error on -next.

Fix this error by simply hardcoding the clock index in the example,
before the breakage spreads any further.

dd71cd4dd6 spi: Add Nuvoton WPCM450 Flash Interface Unit (FIU) bindings 
The Flash Interface Unit (FIU) is the SPI flash controller in the
Nuvoton WPCM450 BMC SoC. It supports four chip selects, and direct
(memory-mapped) access to 16 MiB per chip. Larger flash chips can be
accessed by software-defined SPI transfers.

The FIU in newer NPCM7xx SoCs is not compatible with the WPCM450 FIU.
