[PATCH v4 2/2] remoteproc: wkup_m3: Set deny_sysfs_ops flag

From: Suman Anna <s-anna at ti.com>

The Wakeup M3 remote processor is controlled by the wkup_m3_ipc
client driver, so set the newly introduced 'deny_sysfs_ops' flag
to not allow any overriding of the remoteproc firmware or state
from userspace.
