Subject: [PATCH] media: sti/c8sectpfe: Make use of the helper function devm_platform_ioremap_resource_byname()

Use the devm_platform_ioremap_resource_byname() helper instead of
calling platform_get_resource_byname() and devm_ioremap_resource()
separately

I'm very sorry for it, please forget this patch-sti/c8sectpfe.

I have deleted the "struct resource *res;", if 'res' is used
anywhere, compiler will complain,then I should fix it.
But, in this case, I miss sti/c8sectpfe
