hw/arm/fsl-imx8mp: Derive struct FslImx8mpState from TYPE_SYS_BUS_DEVICE

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