Four mailbox properties are implemented as follows:
1. Customer OTP: GET_CUSTOMER_OTP and SET_CUSTOMER_OTP
2. Device-specific private key: GET_PRIVATE_KEY and
SET_PRIVATE_KEY.
The customer OTP is located in the rows 36-43. The device-specific private key
is located in the rows 56-63.
The customer OTP can be locked with the magic numbers 0xffffffff 0xaffe0000
when running the SET_CUSTOMER_OTP mailbox command. Bit 6 of row 32 indicates
this lock, which is undocumented. The lock also applies to the device-specific
private key.

This query copies the kernel command line into the message buffer. It
was previously stubbed out to return empty, this commit makes it reflect
the arguments specified with `-append`.
I observed the following peculiarities on my Pi 3B+:
- If the buffer is shorter than the string, the response header gives
the full length, but no data is actually copied.
- No NUL terminator is added: even if the buffer is long enough to fit
one, the buffer's original contents are preserved past the string's
end.
- The VC firmware adds the following extra parameters beside the
user-supplied ones (via /boot/cmdline.txt): `video`, `vc_mem.mem_base`
and `vc_mem.mem_size`. This is currently not implemented in qemu.

Some typedefs and macros are defined after the type check macros.
This makes it difficult to automatically replace their
definitions with OBJECT_DECLARE_TYPE.
Patch generated using:
$ ./scripts/codeconverter/converter.py -i \
--pattern=QOMStructTypedefSplit $(git grep -l '' -- '*.[ch]')
which will split "typdef struct { ... } TypedefName"
declarations.
Followed by:
$ ./scripts/codeconverter/converter.py -i --pattern=MoveSymbols \
$(git grep -l '' -- '*.[ch]')
which will:
- move the typedefs and #defines above the type check macros
- add missing #include "qom/object.h" lines if necessary

The property channel driver now interfaces with the framebuffer device
to query and set framebuffer parameters. As a result of this, the "get
ARM RAM size" query now correctly returns the video RAM base address
(not total RAM size), and the ram-size property is no longer relevant
here.

Return a valid value from the BCM2835 property mailbox query "get board
revision". This query is used by U-Boot. Implementing it fixes the first
obvious difference between qemu and real HW.
The value returned is currently hard-coded to match the RPi2 I own. Other
values are legal, e.g. different board manufacturer field values are
likely to exist in the wild.

This sits behind the mailbox interface, and implements
request/response queries for system properties. The
framebuffer-related properties will be added in a later patch.
