ata: libahci_platform: Convert to using platform devm-ioremap methods
Currently the IOMEM AHCI registers space is mapped by means of the
two functions invocation: platform_get_resource() is used to get the very
first memory resource and devm_ioremap_resource() is called to remap that
resource. Device-managed kernel API provides a handy wrapper to perform
the same in single function call: devm_platform_ioremap_resource().
While at it seeing many AHCI platform drivers rely on having the AHCI CSR
space marked with "ahci" name let's first try to find and remap the CSR
IO-mem with that name and only if it fails fallback to getting the very
first registers space platform resource.
