mailbox: imx: add i.MX8 SECO MU support
i.MX8/8X SECO firmware IPC is an implementation of passing messages.
But current imx-mailbox driver only support one word message,
i.MX8/8X linux side firmware has to request four TX, four RX and a
TXDB to support IPC to SECO firmware. This is low efficent and
more interrupts triggered compared with one TX and one RX.
To make SECO MU work,
- parse the size of msg.
- Only enable TR0/RR0 interrupt for transmit/receive message.
- For TX/RX, only support one TX channel and one RX channel
- For RX, support receive msg of any size, limited by hardcoded value
of 30.
