    remoteproc: stm32: Fix incorrect type in assignment for va
    
    [ Upstream commit 32381bbccba4c21145c571701f8f7fb1d9b3a92e ]
    
    The sparse tool complains about the attribute conversion between
    a _iomem void * and a void *:
    
    stm32_rproc.c:122:12: sparse: sparse: incorrect type in assignment (different address spaces) @@     expected void *va @@     got void [noderef] __iomem * @@
    stm32_rproc.c:122:12: sparse:     expected void *va
    stm32_rproc.c:122:12: sparse:     got void [noderef] __iomem *
    
    Add '__force' to explicitly specify that the cast is intentional.
    This conversion is necessary to cast to virtual addresses pointer,used,
    by the remoteproc core.
