pflash_cfi01_register() hides an implicit sysbus mapping of MMIO region #0. This is not practical in a heterogeneous world where multiple cores use different address spaces. In order to remove to remove pflash_cfi01_register() from the pflash API, open-code it as a qdev creation call followed by an explicit sysbus mapping.
