MLK-21415 can: flexcan: add Tx support for variable payload size

Now the FlexCAN driver always use last mailbox for TX, it will work well when
MB payload size is 8/16 bytes. TX mailbox would change to 13 when MB payload
size is 64 bytes to support CANFD. So we may need to set iflag register to add
support for variable payload size.
