bsp: nxp/mcx: Use standard SPI CS pin. (#9312) 

* bsp: nxp/mcx/mcxn: SPI: Added missing bracket and re-format code.

The closing bracket is missing from SPI6 struct.
Introduced since commit fc1cfd6d3627ba8460d514e7913bd307e8b1d567 .

Use standard rt_spi_device->cs_pin instead of user_data pointer.
