can: c_can_platform: Fix raminit, use devm_ioremap() instead of devm_ioremap_resource()
The raminit register is shared register for both can0 and can1. Since commit:
32766ff net: can: Convert to use devm_ioremap_resource
devm_ioremap_resource() is used to map raminit register. When using both
interfaces the mapping for the can1 interface fails, leading to a non
functional can interface.
