ata: ahci_da850: use devm_platform_ioremap_resource()

Replace the open-coded platform_get_resource(IORESOURCE_MEM, 1) plus
devm_ioremap() sequence with devm_platform_ioremap_resource(pdev, 1),
which looks up resource index 1 (the power-down control register),
reserves it and maps it in one call, returning an ERR_PTR checked with
IS_ERR()/PTR_ERR(). Resource index 0 (the AHCI register block) is still
mapped separately as hpriv->mmio via ahci_platform_get_resources().

Built for ARM (davinci_all_defconfig + CONFIG_AHCI_DA850) with LLVM=1;
drivers/ata/ahci_da850.o compiles cleanly.
