soc: ti: wkup_m3_ipc: Send NULL dummy message instead of pointer message
[ Upstream commit ddbf3204f600a4d1f153498f618369fca352ae00 ]
mbox_send_message() sends a u32 bit message, not a pointer to a message.
We only convert to a pointer type as a generic type. If we want to send
a dummy message of 0, then simply send 0 (NULL).
