mailbox: add list of used channels to debugfs
During development, it is useful to see which mailboxes are currently
obtained. Use a seq-file in debugfs to list the currently registered
controllers and their used channels. Example output from a Renesas R-Car
X5H based system:
# cat /sys/kernel/debug/mailbox/mailbox_summary
189e0000.system-controller:
0: c1000000.mailbox_test_send_to_recv
1: c1000100.mailbox_test_recv_to_send
128: c1000100.mailbox_test_recv_to_send
129: c1000000.mailbox_test_send_to_recv
189e1000.system-controller:
4: scmi_dev.1
5: scmi_dev.2
