[ Upstream commit c77b35ce66af25bdd6fde60b62e35b9b316ea5c2 ]
The sparse tool complains about the remove of the _iomem attribute.
stm32_rproc.c:660:17: warning: cast removes address space '__iomem' of expression
Add '__force' to explicitly specify that the cast is intentional.
This conversion is necessary to cast to addresses pointer,
which are then managed by the remoteproc core as a pointer to a
resource_table structure.
Fixes: 8a471396d21c ("remoteproc: stm32: Move resource table setup to rproc_ops")
