cx18: Improve handling of outgoing mailboxes detected to be busy
From: Andy Walls <awalls@radix.net>
cx18: Improve handling of outgoing mailboxes detected to be busy. When
encountering a busy mailbox, sleep instead of polling, and wait for interrupt or
timeout. If the mailbox is still busy, force it free. When sending commands,
make sure we never create a situation where we mark the mailbox busy upon
sending, and ensure we always have a method to cleanly recover from a busy
mailbox.
Priority: high
