ata: sata_highbank: use devm_platform_ioremap_resource

Replace the open-coded platform_get_resource() plus devm_ioremap()
sequence with devm_platform_ioremap_resource(), which fetches the
resource, requests the region and maps it in one call. Switch the error
check to IS_ERR()/PTR_ERR() and drop the now-unused struct resource
pointer.

There is a single IORESOURCE_MEM resource, and the SATA PHY registers
are mapped separately via of_iomap() from distinct DT nodes, so the
region reservation added by devm_ioremap_resource() is exclusive and
does not introduce overlap failures.

The mem-based ata_port_desc() line is dropped along with the resource
pointer; the remaining per-port description is retained.

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