[PATCH 10/20] hw/arm: Open-code pflash_cfi01_register()

["Philippe Mathieu-Daudé" <philmd@linaro.org>]

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.
