db1015e92e Move QOM typedefs and add missing includes
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

0a258e9461 aspeed_timer: Fix ASPEED_TIMER macro definition
The macro definition had an extra semicolon.  This was never
noticed because the macro was only being used where it didn't
make a difference.

fadefada4d aspeed/timer: Add support for IRQ status register on the AST2600
The AST2600 timer replaces control register 2 with a interrupt status
register. It is set by hardware when an IRQ occurs and cleared by
software.

Modify the vmstate version to take into account the new fields.

Based on previous work from Joel Stanley.

c20375dd86 aspeed/timer: Add AST2600 support
The AST2600 timer has a third control register that is used to
implement a set-to-clear feature for the main control register.

On the AST2600, it is not configurable via 0x38 (control register 3)
as it is on the AST2500.

d85c87c1d1 aspeed/timer: Add support for control register 3
The AST2500 timer has a third control register that is used to
implement a set-to-clear feature for the main control register.

This models the behaviour expected by the AST2500 while maintaining
the same behaviour for the AST2400.

The vmstate version is not increased yet because the structure is
modified again in the following patches.

9b945a9ee3 aspeed/timer: use the APB frequency from the SCU
The timer controller can be driven by either an external 1MHz clock or
by the APB clock. Today, the model makes the assumption that the APB
frequency is always set to 24MHz but this is incorrect.

The AST2400 SoC on the palmetto machines uses a 48MHz input clock
source and the APB can be set to 48MHz. The consequence is a general
system slowdown. The QEMU machines using the AST2500 SoC do not seem
impacted today because the APB frequency is still set to 24MHz.

We fix the timer frequency for all SoCs by linking the Timer model to
the SCU model. The APB frequency driving the timers is now the one
configured for the SoC.

c04bd47db6 hw/timer: Add ASPEED timer device model
Implement basic ASPEED timer functionality for the AST2400 SoC[1]: Up to
8 timers can independently be configured, enabled, reset and disabled.
Some hardware features are not implemented, namely clock value matching
and pulse generation, but the implementation is enough to boot the Linux
kernel configured with aspeed_defconfig.
