hw/riscv/sifive_e: Fix inheritance of SiFiveEState

Browse Source 
SiFiveEState inherits from SysBusDevice while it's TypeInfo claims it to
inherit from TYPE_MACHINE. This is an inconsistency which can cause
undefined behavior such as memory corruption.

Change SiFiveEState to inherit from MachineState since it is registered
as a machine.

Fixes: 0869490b1c ("riscv: sifive_e: Manually define the machine")
