- Support T8015's ASC mailboxes as well as "AKF" mailboxes
- Make the SEP interface work with AKF mailboxes

AKF (Apple KingFisher) mailboxes are used for Cortex-A7 coprocessors in A7 - A10, T2 SoCs. There are two revisions of this hardware. Since the message size of this mailbox is 64-bit instead of 96-bit, support this type of mailbox in its own file as all clients will need to be modified to support the smaller message size.

Abstract SEP message from the underlying mailbox such that support for SEP behind different types of mailbox can be added. Signed-off-by: Nick Chan <towinchenmi@gmail.com>
Some SEP features are not supported on older implementations. Add a capability framework to communicate that to downstream clients. Signed-off-by: Nick Chan <towinchenmi@gmail.com>
Add support for SEP behind AKF mailboxes. AKF mailbox has 64-bit (32+32) bit messages so both msg0 and msg1 is used for transmitting SEP messages. Signed-off-by: Nick Chan <towinchenmi@gmail.com>
