LF-933 crypto: caam - fix iosource busy issue 

The caam controller driver claims the ownership of the
whole caam register space due to which while binding the
Job Ring to fsl-jr-uio driver, it returns IOSOURCE_BUSY
error.

This patch replaces devm_request_mem_region() API with
platform_get_resource() to avoid this issue.

Fixes: eb5e94d462 ("crypto: caam - use devres to unmap memory")
