[Qemu-devel] [PATCH 1/3] pflash_cfi01: add pflash_cfi01_init

[Max Filippov <jcmvbkbc@gmail.com>]

pflash_cfi01_register always registers FLASH to the default
system_memory region, which may not always be the right thing.

Provide pflash_cfi01_init function that only creates FLASH device and
sets its properties, leaving MMIO region registration to its caller.
