[PATCH v4 00/37] Clean-ups: qom-ify serial and remove QDEV_PROP_PTR

["Marc-André Lureau" <marcandre.lureau@redhat.com>]

Hi,

QDEV_PROP_PTR is marked in multiple places as "FIXME/TODO/remove
me". In most cases, it can be easily replaced with QDEV_PROP_LINK when
the pointer points to an Object.

There are a few places where such substitution isn't possible. For
those places, it seems reasonable to use a specific setter method
instead, and keep the user_creatable = false. In other places,
proper usage of qdev or other facilies is the solution.

The serial code wasn't converted to qdev, which makes it a bit more
archaic to deal with. Let's convert it first, so we can more easily
embed it from other devices, and re-export some properties and drop
QDEV_PROP_PTR usage.

v4: (after Peter & Philippe reviews)
 - replaced "self" variable names with abbreviations
 - split "mips: inline serial_init()"
 - new patches: "mips: use sysbus_mmio_get_region() instead of internal
   fields", "leon3: use qdev gpio facilities for the PIL", "qdev: use
   g_strcmp0() instead of open-coding it", "qdev/qom: remove some TODO
   limitations now that PROP_PTR is gone"
 - dropped patches: "sparc: move PIL irq handling to cpu.c" & "serial:
   add "instance-id" property"
 - various comments / commit message tweaks
 - added r-b tags

v3:
 - introduce SerialMM and SerialIO sysbus devices
 - remove serial_mm_connect introduced in v2
 - replace "base" property introduced in v2, use "instance-id" for
   vmstate purpose only
 - add a few preliminary clean-ups

v2:
 - qom-ify serial
 - embed the serial from sm501, and expose a "chardev" property
 - add "leon3: use qemu_irq framework instead of callback as property"
 - add "sparc: move PIL irq handling to cpu.c"
 - add "cris: improve passing PIC interrupt vector to the CPU"
 - misc comment/todo changes, add r-b tags
