A transmit FIFO can never be full, because the mailbox framework
waits until mbox->ops->last_tx_done() succeeds before sending the next
message. sun6i_msgbox_last_tx_done() ensures that the FIFO is empty.
Since the extra check here is unnecessary, remove it.

Instead of ad-hoc variant ID checks throughout the code, let's start
moving the variant-specific details to a match structure. This allows
for future flexibility, and it better matches the other axp20x power
supply drivers.

Like the APB0 clock on previous chips, this is a simple single-parent
clock with an M divider. Use the equivalent helper macro instead of
writing out the whole clock description manually.

The H3 and H5 SoCs contain a message box that can be used to send
messages and interrupts back and forth between the ARM application CPUs
and the ARISC coprocessor. Add a device tree node for it.

Note that since the mailbox framework only supports a single phandle
with each name (mbox_request_channel_byname always returns the first
one), this new mode only supports a single SCPI channel.

This mailbox hardware is present in Allwinner sun6i, sun8i, sun9i, and
sun50i SoCs. Add a device tree binding for it. As it has only been
tested on the A83T, A64, H3/H5, and H6 SoCs, only those compatibles are
included.

With this patch, all transfers reliably succeed during/after resume.
