Subject: chardev: generate an internal id when none given

Internally, qemu may create chardev without ID. Those will not be
looked up with qemu_chr_find(), which prevents using qdev_prop_set_chr().

Use id_generate(), to generate an internal name (prefixed with #), so
no conflict exist with user-named chardev.

Subject: serial: initial qom-ification

Make SerialState a device (the following patches will introduce IO/MM
sysbus serial devices)

None of the serial_{,mm}_init() callers actually free the returned
value (even if they did, it would be quite harmless), so we can change
the object allocation at will.

However, the devices that embed SerialState must now have their field
QOM-initialized manually (isa, pci, pci-multi).

Subject: serial: start making SerialMM a sysbus device

Memory mapped serial device is in fact a sysbus device. The following
patches will make use of sysbus facilities for resource and
registration. In particular, "serial-mm: use sysbus facilities" will
move internal serial realization to serial_mm_realize callback to
follow qdev best practices.

Subject: serial-mm: add "regshift" property

And a property and rename "it_shift" field to "regshift", as it seems
to be more popular (and I don't know what "it" stands for).

Subject: mips: inline serial_init()

The function is specific to mipssim, let's inline it.

(when inlining, we use a DeviceState variable instead of SerialIO, as
it is the most common type used, and avoids having too many casts)

Subject: etraxfs: remove PROP_PTR usage

etraxfs_dma_client are not Object, so can't be exposed to user with
QOM path. Let's remove property usage and move the constructor to the
.c unit, simplifying some code on the way.

Subject: omap-intc: remove PROP_PTR

Since clocks are not QOM objects, replace PROP_PTR of clocks with
setters methods.

(in theory there should probably be different methods for omap1 &
omap2 intc, but this is left as a future improvement)

Subject: qdev: remove PROP_MEMORY_REGION

PROP_MEMORY_REGION was a derivative of PROP_PTR, added in commit
ed03d749f3f513b8fb0287757cfda2cb6825f063 (qdev: add MemoryRegion
property) and thankfully no longer needed since commit
3eff40dbf44896a8180c86c84dbdefb2eb173fbe (hw/misc: Remove
mmio_interface device).

Subject: qdev: remove QDEV_PROP_PTR

No longer used in the tree. The comment about user_creatable is still
quite relevant, but there is already a similar comment in qdev-core.h.
