[PATCH 17/20] hw/arm: Open-code pflash_cfi02_register()

[Philippe Mathieu-Daudé]

pflash_cfi02_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_cfi02_register() from the pflash API,
open-code it as a qdev creation call followed by an explicit
sysbus mapping.
