Subject: [PATCH 5.14 823/849] remoteproc: Fix the wrong default value of is_iomem

From: Dong Aisheng <aisheng.dong@....com>

commit 970675f61bf5761d7e5326f6e4df995ecdba5e11 upstream.

Currently the is_iomem is a random value in the stack which may
be default to true even on those platforms that not use iomem to
store firmware.
