[PATCH] spi: ath79: simplify iomem resource mapping

[Heiner Kallweit <hkallweit1@xxxxxxxxx>]

Simplify the code by switching from devm_ioremap to devm_ioremap_resource.
Checking the result of platform_get_resource is not needed as
devm_ioremap_resource checks the provided resource argument for NULL.
