staging: ccree: Convert to devm_ioremap_resource for map, unmap

Browse source

It is recommended to use managed function devm_ioremap_resource(),
which simplifies driver cleanup paths and driver code.
This patch does the following:
(a) replace request_mem_region(), ioremap() and corresponding error
handling with devm_ioremap_resource().
(b) remove struct resource pointer(res_mem) in struct ssi_drvdata as it
seems redundant, use struct resource pointer which is defined locally and
adjust return value of platform_get_resource() accordingly.
(c) release_mem_region() and iounmap() are dropped, since devm_ioremap_
resource() releases and unmaps mem region on driver detach.
(d) adjust log messages accordingly and remove any blank lines.
