[Qemu-devel] [PATCH v5 3/5] PC: use qdev_xx to create hpet instead of sysbus_create_xx

[Liu Ping Fan]

sysbus_create_xx func does not allow us to set a device's extra
properties.  While hpet need to set its compat property before
initialization, so we abandon the wrapper function, and spread
its logic "inline"
