Add basic support for S32V234 SIUL2 pin controller, based on i.MX model. Definitions of MSCR PADs, which are used for I/O (MSCR < 512), were added. Definitions of IMCR (input only) PADs (MSCR >= 512), corresponding to specific peripherals like ENET, I2C, UART or uSDHC are going to be added along with the drivers which need them. Add configurations for specific S32 SoC selection and pinmuxing driver.
