The current code doesn't check whether platform_get_resource_byname()
succeeded to get the l1tcm memory, which is optional, before attempting
to map it. This results in the following error message when it is
missing:

mtk-scp 10500000.scp: error -EINVAL: invalid resource (null)

Add a check so that the remapping is only attempted if the memory region
exists. This also allows to simplify the logic handling failure to
remap, since a failure then is always a failure.
