[nxp/mcxn] add SPI6 support (#8704)
* [bsp][nxp] add missing drv_spi.h

Otherwise when building spi users such as u8g2, gcc will complain can't
find the drv_spi.h.

* [bsp][nxp] enable spi6

* [bsp][nxp] add spi sample code which uses spi6 to loopback

Connect spi6's MISO <--> MSIO, I.E P3_20 and P3_22 with Dupont Line
The sample usage and output would be:

msh >spi_sample
spi rbuf : 0 1 2 3 4 5 6 7 8 9 a b c d e f 10 11 12 13 14 15 16 17 18 19 1a 1b 1c 1d 1e 1f

spi loopback mode test over!
