[RESEND v5 3/4] platform/chrome: cros_ec_debugfs: Fix permissions for panicinfo

[Avadhut Naik]

From: Avadhut Naik <Avadhut.Naik@xxxxxxx>

The debugfs_create_blob() function has been used to create read-only binary
blobs in debugfs. The function filters out permissions, other than S_IRUSR,
S_IRGRP and S_IROTH, provided while creating the blobs.

The very behavior though is being changed through previous patch in the
series (fs: debugfs: Add write functionality to debugfs blobs) which makes
the binary blobs writable.

As such, rectify the permissions of panicinfo file to ensure it remains
read-only.
