[ARM] rpc: acornscsi: update to new style ecard driver

Update acornscsi as per all the other ecard drivers to use MMIO
accessors rather than the obsolete 'pc io' style inb/outb accessors.

Use ecard_request_resources()/ecard_release_resources() for easier
resource handling, rather than requesting 5 separate regions
individually.
