[PATCH v4 4/5] hw/char/sh_serial: Remove dummy definition of SH_SERIAL class

[Zhenzhong Duan <zhenzhong.duan@intel.com>]

SH_SERIAL is declared with OBJECT_DECLARE_SIMPLE_TYPE but defined with
OBJECT_DEFINE_TYPE, SHSerialStateClass is also a dummy class which
missed its parent.

Change to use OBJECT_DEFINE_SIMPLE_TYPE and remove SHSerialStateClass.
