drivers: provide devm_platform_get_and_ioremap_resource()

Browse Source 
Since commit "drivers: provide devm_platform_ioremap_resource()",
it was wrap platform_get_resource() and devm_ioremap_resource() as
single helper devm_platform_ioremap_resource(). but now, many drivers
still used platform_get_resource() and devm_ioremap_resource()
together in the kernel tree. The reason can not be replaced is they
still need use the resource variables obtained by platform_get_resource().
so provide this helper.
