Philippe Mathieu-Daudé 739fa32554 hw/qdev-clock: Avoid calling qdev_connect_clock_in after DeviceRealize
Clock canonical name is set in device_set_realized (see the block
added to hw/core/qdev.c in commit 0e6934f264).
If we connect a clock after the device is realized, this code is
not executed. This is currently not a problem as this name is only
used for trace events, however this disrupt tracing.

Add a comment to document qdev_connect_clock_in() must be called
before the device is realized, and assert this condition.

Philippe Mathieu-Daudé f129360ca1 hw/qdev-clock: Uninline qdev_connect_clock_in()
We want to assert the device is not realized. To avoid overloading
this header including "hw/qdev-core.h", uninline the function first.

Damien Hedde f0bc2a64c0 qdev-clock: introduce an init array to ease the device construction
Introduce a function and macro helpers to setup several clocks
in a device from a static array description.

An element of the array describes the clock (name and direction) as
well as the related callback and an optional offset to store the
created object pointer in the device state structure.

The array must be terminated by a special element QDEV_CLOCK_END.

This is based on the original work of Frederic Konrad.

Damien Hedde 0e6934f264 qdev: add clock input&output support to devices.
Add functions to easily handle clocks with devices.
Clock inputs and outputs should be used to handle clock propagation
between devices.
The API is very similar the GPIO API.

This is based on the original work of Frederic Konrad.
