Subject: [PATCH v2 1/2] platform: goldfish: Allow goldfish drivers for archs
 with IOMEM and DMA

We don't need explicit dependency of Goldfish kconfig option on various
architectures. Instead, the Goldfish kconfig option should only depend
on HAS_IOMEM and HAS_DMA which is sufficient for all Goldfish devices.

 	  Say Y here to get to see options for the Goldfish virtual platform.
 	  This option alone does not add any kernel code.
