Subject: [can-next PATCH 1/1] net: can: c_can_platform: Use devm_ioremap instead of devm_ioremap_resource.

From: George Cherian <george.cherian@...com>

The raminit register is shared register for both can0 and can1.
Using devm_ioremap_resource fails the mapping for can1 interface
leading to a non functional can interface.
