bsp: k230: add spi driver

Requirement: The BSP for the k230 platform in the RT-Thread repository does not yet have an spi driver.

Solution: Provide spi driver for the k230 platform in the RT-Thread repository.

- Supports SPI0(OSPI) controller with 1/2/4/8 data lines.
- Supports SPI1(QSPI0) and SPI2(QSPI1) controllers with 1/2/4 data lines.
- Implements DMA-based transfers for OSPI, QSPI, and DSPI modes.
- Falls back to standard IRQ-driven transfers for legacy SPI mode (single line).
- Updates documentation in bsp/README.md
