Add the appropriate compatible string, and document the new reg
properties of the AST2700 FSI controller, which can directly access
the FSI controller registers as well as the FSI link address space.

Since there are multiple FSI controllers documented, the common
properties should be documented separately and then referenced
from the specific controller documentation. Add bus-frequency for
the FSI bus and CFAM local bus frequencies. Add interrupt
controller properties.

The FSI2SPI bridge has several SPI controllers behind it, which
should be documented. Also, therefore the node needs to specify

Another round of wack-a-mole. The json-schema default is additional
unknown properties are allowed, but for DT all properties should be
defined.

Clean-up incorrect indentation, extra spaces, long lines, and missing
EOF newline in schema files. Most of the clean-ups are for list
indentation which should always be 2 spaces more than the preceding
keyword.
Found with yamllint (which I plan to integrate into the checks).

This isn't per-se a real device, it's a pseudo-device that
represents the use of the Aspeed built-in ColdFire to
implement the FSI protocol by bitbanging the GPIOs instead
of doing it from the ARM core.
Thus it's a drop-in replacement for the existing
fsi-master-gpio pseudo-device for use on systems based
on the Aspeed chips. It has most of the same properties,
plus some more needed to operate the coprocessor.

This change introduces a proposed layout for describing FSI busses in
the device tree. While the bus is probe-able, we'd still like a method
of describing subordinate (eg i2c) busses that are behind FSI devices.
The FSI core will be responsible for matching probed slaves & engines to
their device tree nodes, so the FSI device drivers' probe() functions
will be passed a struct device with the appropriate of_node populated
where a matching DT node is found.
