[PATCH v2 1/2] spi: dt-bindings: nuvoton,wpcm450-fiu: Fix error in example (bogus include)

[Jonathan Neuschäfer]

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.

  me aware that it is a problem that has found its way into linux-next)
