omap: mailbox: convert block api to kfifo
The underlying buffering implementation of mailbox is converted from block API to kfifo due to the simplicity and speed of kfifo. The default size of the kfifo buffer is set to 256 bytes. This value is configurable at compile time (via CONFIG_OMAP_MBOX_KFIFO_SIZE), and can be changed at runtime (via the mbox_kfifo_size module parameter).
