spi: dt-bindings: nuvoton,ma35d1-qspi: Disallow GPIO chip selects

Browse Source 
The generic SPI controller binding allows GPIO-based chip selects, but
the MA35D1 QSPI driver currently supports only the controller's native
chip selects.

Disallow the cs-gpios property so that the binding matches the
functionality provided by the driver.
