eda40cc168 fsl_imx*: Migrate ROM contents
The fsl-imx* boards accidentally forgot to register the ROM memory
regions for migration.  This used to require a manual step of calling
vmstate_register_ram(), but following commits
1cfe48c1ce21..b08199c6fbea194 we can use memory_region_init_rom() to
have it do the migration for us.

This is a migration break, but the migration code currently does not
handle the case of having two RAM regions which were not registered
for migration, and so prior to this commit a migration load would
always fail with:
  "qemu-system-arm: Length mismatch: 0x4000 in != 0x18000: Invalid argument"

NB: migration appears at this point to be broken for this board
anyway -- it succeeds but the destination hangs; probably some
device in the system does not yet support migration.

98a99ce084 hw: Use new memory_region_init_{ram, rom, rom_device}() functions
Use the new functions memory_region_init_{ram,rom,rom_device}()
instead of manually calling the _nomigrate() version and then
vmstate_register_ram_global().

Patch automatically created using coccinelle script:
 spatch --in-place -sp_file scripts/coccinelle/memory-region-init-ram.cocci -dir hw

(As it turns out, there are no instances of the rom and
rom_device functions that are caught by this script.)

1cfe48c1ce memory: Rename memory_region_init_ram() to memory_region_init_ram_nomigrate()
Rename memory_region_init_ram() to memory_region_init_ram_nomigrate().
This leaves the way clear for us to provide a memory_region_init_ram()
which does handle migration.

53d6e53189 arm: remove remaining cannot_destroy_with_object_finalize_yet
With commit ce5b1bbf62 ("exec: move cpu_exec_init() calls to
realize functions"), we can now remove all the
remaining cannot_destroy_with_object_finalize_yet as
unsafe references have been moved to cpu_exec_realizefn().
(tested with QOM command provided by commit 4c315c27).

b4948be93e char: remove init callback
The CharDriverState.init() callback is no longer set since commit
a61ae7f88c and thus unused. The only user, the malta FGPA display has
been converted to use an event "opened" callback instead.

66542f6399 i.MX: split the GPT timer implementation into per SOC definitions
In various Freescale SOCs, the GPT timers can be configured to select
its input clock.

Depending on the SOC the set of available input clocks may vary.

The actual single GPT definition was no good enough and because of it
booting the sabrelite board with a i.MX6DL device tree would fail
because of an incorrect input clock definition for the i.MX6DL SOC.

This patch fixes the i.MX6DL boot failure by adding the ability to
define a different set of input clocks depending on the considered SOC.

A different class has been defined for i.MX25, i.MX31 and i.MX6 each with
its specific set of input clocks.

The patch has been tested by booting KZM, i.MX25 PDK, i.MX6Q sabrelite
and i.MX6DL sabrelite.

a7aeb5f7b2 imx: Use memory_region_init_rom() for ROMs
The imx boards were all incorrectly creating ROMs using
memory_region_init_rom_device() with a NULL ops pointer. This
will cause QEMU to abort if the guest tries to write to the
ROM. Switch to the new memory_region_init_rom() instead.
