[PATCH v2 1/2] resource: Replace printk(KERN_WARNING) by pr_warn(), printk() by pr_info()

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

Replace printk(KERN_WARNING) by pr_warn() and printk() by pr_info().

While at it, use %pa for the resource_size_t variables. With that,
for the sake of consistency, introduce a temporary variable for
the end address in iomem_map_sanity_check() like it's done in another
function in the same module.
