Example S32K324 STANDBY wake up using CAN-0-RX and GPIO Switch DS3.5 RTD300

*******************************************************************************

The purpose of this demo application is to present a usage of the
POWER & WKUP IP Driver for the S32K3xx MCU.

In current example :--
SW-5 = PTB-26 -----> PRESS to enter the STANDBY mode.
SW-6 = PTB-19 = WKUP[38] --> PRESS to exit the STANDBY mode.
CAN-0-RX = PTA-6 = WKUP[15] --> send CAN message to exit the STANDBY mode

The example uses PIT-0 timer, to generate the periodic interrupt.

The example uses FLEXCAN-0 for transmit & receive using following Message buffer :--
#define RX_MB_IDX_0 10U
#define RX_MB_IDX 11U
#define TX_MB_IDX 12U

BAUDRATE : 500 KBPS

Wake-up source, CAN-0-RX :--
According to the IOMUX table in RM, for example, PTA6 can be used as WKPU15 and CAN0_RX. It means that the WKPU15 input doesn't require specific MSCR configuration.
So if its input buffer is enabled and the corresponding WKPU input channel is enabled/configured in the WKPU, it should be able to act as wake-up input.
