OvmfPkg: CloudHv: Rely on QemuFwCfgLibNull implementation

Since Cloud Hypervisor doesn't support the fw_cfg mechanism, it's more
appropriate to rely on QemuFwCfgLibNull implementation of QemuFwCfgLib
since it provides a null implementation that will not issue any PIO
accesses to ports 0x510 and 0x511.
