spi: ppc4xx: devm-ify probe and drop manual resource management

Browse source

Replace open-coded resource handling with devm helpers:
  - spi_alloc_host -> devm_spi_alloc_host
  - of_address_to_resource + ioremap + request_mem_region
    -> devm_platform_ioremap_resource
  - request_irq -> devm_request_irq
  - remove now-unused mapbase/mapsize fields from struct ppc4xx_spi
  - move of_node_put(opbnp) earlier to simplify error paths
  - delete the entire error-unwinding goto chain

Move devm_platform_ioremap_resource() and platform_get_irq() up in order
to avoid doing work if -EPROBE_DEFER is returned.
