ata: pata_pxa: use devm_platform_ioremap_resource

Replace the open-coded platform_get_resource() plus devm_ioremap()
sequences for the CMD and CTL ports with devm_platform_ioremap_resource(),
which fetches the resource, requests the region and maps it in one call.
Switch the error checks to IS_ERR()/PTR_ERR() accordingly and drop the
now-unused cmd_res and ctl_res variables.

The DMA port keeps using devm_ioremap() as its resource is
IORESOURCE_DMA. The CMD (res 0) and CTL (res 1) MEM resources are
disjoint in the ATA task-file layout, so the added region reservation
in devm_ioremap_resource() does not introduce overlap failures.

Built for ARM (drivers/ata/pata_pxa.o) with LLVM=1.
