[PATCH v2] hw/arm: Adjust some coding styles about memory hotplug

[PATCH v2] hw/arm: Adjust some coding styles about memory hotplug

[Keqian Zhu]

From: zhukeqian <zhukeqian1@huawei.com>

There is extra indent in ACPI GED plug cb. And we can use
existing helper function to trigger hotplug handler plug.

FYI one does not need to repost v2 for the purpose of
picking up tags, usually maintainer takes care of that
when patch is queued
