Introduce a new Kconfig CONFIG_PLATFORM_OP, which shall only be disabled
on some dom0less systems or PV shim on x86, to reduce Xen footprint.
The consequence of introducing "CONFIG_PLATFORM_OP=y" in .config file
generated from pvshim_defconfig is transient, which will be adjusted in
the final patch.
