ps：在设备初始化阶段不应该存在对硬件的操作
你的解决方案是什么 (what is your solution)
ps：添加一个pin_init函数，在spi设备使用时调用该函数来完成硬件引脚的状态初始化，而不是在设备初始化阶段对硬件进行操作，已经在瑞萨HMI上通过验证
* [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!

This patch adds support for PWM generation using CTIMER on MCXN devices.
Each CTIMER provides 4 PWM channels, channels sharing the same
CTIMER instance will have the same period settings, and the duty
cycle will be maintained if period is changed through one of the four
channels.
The period channel is automatically assigned and will be transferred
to one of the other available channels if that channel is used for PWM
generation, no glitches should be expected during the transition.
The patch also provides a sample PWM output configuration connected to
the on-board green LED which can be enabled through Kconfig.

This patch adds support for hwtimer using MRT0 instance which simulates
4 independent timers. The frequency is fixed to AHB bus frequency and
not adjustable.
