[PATCH v2 1/5] boot/image-android: Workaround kernel/ramdisk invalid addr

[George Chan via B4 Relay <devnull+gchan9527.gmail.com@kernel.org>]

From: George Chan <gchan9527@gmail.com>

Some androidboot image have invalid kernel/ramdisk load addr,
force to ignore those value and use loadaddr instead.
