The PRAM/RTC is accessed using clock and data pins on q800 VIA1 port B and so
can be moved to MOS6522Q800VIA1State.

According to the "Guide To The Macintosh Family Hardware", the 60Hz VIA1 timer
on newer Macs such as the Quadra only exists for compatibility with old software
and is no longer synced to the VBL interval.
Rename the VBL timer to 60Hz timer to emphasise this and to prevent confusion
when the real VBL interrupt (now handled as a NuBus slot interrupt) is added in
future.

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 existing ADB state machine is designed to work with Linux which has a different
interpretation of the state machine detailed in "Guide to the Macintosh Family
Hardware". In particular the current Linux implementation includes an extra change
to IDLE state when switching the VIA between send and receive modes which does not
occur in MacOS, and omitting this transition causes the current mac_via ADB state
machine to fail.
Rework the ADB state machine accordingly so that it can enumerate and autopoll the
ADB under both Linux and MacOS, including the addition of the new adb_autopoll_block()
and adb_autopoll_unblock() functions.

This allows to save and restore the content of the PRAM.
It may be useful if we want to check the configuration or to change it.
The backend is added using mtd interface, for instance:
... -drive file=pram.img,format=raw,if=mtd ...
where pram.img is the file where the data will be stored, its size must
be 256 bytes.

VIA needs to be able to poll the ADB interface and to read/write data
from/to the bus.
This patch adds functions allowing that.

Inside the 680x0 Macintosh, VIA (Versatile Interface Adapter) is used
to interface the keyboard, Mouse, and real-time clock. It also provides
control line for the floppy disk driver, video interface, sound circuitry
and serial interface.
This implementation is based on the MOS6522 object.
