18c86e2b9d hw/core: Clean up includes
Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

This commit was created with scripts/clean-includes.

c72fbf98cb sysbus: Don't use hw_error() in machine_init_done_notifiers
platform_bus_map_irq() and platform_bus_map_mmio() use hw_error() to
fail.  They run in machine_init_done_notifiers, via
platform_bus_init_notify() and link_sysbus_device().  Printing CPU
registers is not helpful there.

Replace hw_error() by error_report(); exit(1).  If these are
programming errors, it should be replaced by an assertion instead.

While there, observe that both functions always return 0, and
link_sysbus_device() ignores the return value.  Change them to void.

7634fe3c27 sysbus: Add new platform bus helper device
We need to support spawning of sysbus devices dynamically via the command line.
The easiest way to represent these dynamically spawned devices in the guest's
memory and IRQ layout is by preallocating some space for dynamic sysbus devices.

This is what the "platform bus" device does. It is a sysbus device that exports
a configurably sized MMIO region and a configurable number of IRQ lines. When
this device encounters sysbus devices that have been dynamically created and not
manually wired up, it dynamically connects them to its own pool of resources.

The machine model can then loop through all of these devices and create a guest
configuration (device tree) to make them visible to the guest.
