spi: dt-bindings: fsl: Correct GPIO flags in the example

IRQ_TYPE_xxx flags are not correct in the context of GPIO flags.
These are simple defines so they could be used in DTS but they will not
have the same meaning: IRQ_TYPE_EDGE_RISING = 1 = GPIO_ACTIVE_LOW.

Correct the example DTS to use proper flags for chip select GPIOs,
assuming the author of the code wanted similar logical behavior:

  IRQ_TYPE_EDGE_RISING => GPIO_ACTIVE_HIGH
