26c1c41e8c hw/arm/fsl-imx8mp: Derive struct FslImx8mpState from TYPE_SYS_BUS_DEVICE
Deriving from TYPE_SYS_BUS_DEVICE fixes the SoC object to be reset upon machine
reset. It also makes the SoC implementation not user-creatable which can trigger
the following crash:

  $ ./qemu-system-aarch64  -M virt -device fsl-imx8mp
  **
  ERROR:../../devel/qemu/tcg/tcg.c:1006:tcg_register_thread: assertion failed:

  Bail out! ERROR:../../devel/qemu/tcg/tcg.c:1006:tcg_register_thread:
  assertion failed: (n < tcg_max_ctxs)
  Aborted (core dumped)

02e5214624 hw/arm/imx8mp-evk: Fix reference count of SoC object
TYPE_FSL_IMX8MP is created using object_new(), so must be realized with
qdev_realize_and_unref() to keep the reference counting intact.

0c105b2615 hw/arm/fsl-imx8mp: Add Ethernet controller
The i.MX 8M Plus SoC actually has two ethernet controllers, the usual ENET one
and a Designware one. There is no device model for the latter, so only add the
ENET one.

a81193c3e9 hw/arm/fsl-imx8mp: Add USDHC storage controllers
The USDHC emulation allows for running real-world images such as those generated
by Buildroot. Convert the board documentation accordingly instead of running a
Linux kernel with ephemeral storage.

a4eefc69b2 hw/arm: Add i.MX 8M Plus EVK board
As a first step, implement the bare minimum: CPUs, RAM, interrupt controller,
serial. All other devices of the A53 memory map are represented as
TYPE_UNIMPLEMENTED_DEVICE, i.e. the whole memory map is provided. This allows
for running Linux without it crashing due to invalid memory accesses.
