Subject: [PATCH v2 2/4] staging: vchiq: Do not assign default dma_mask explicitly

The vchiq driver assigns DMA_BIT_MASK(32) to the child platform devices
it registers. By default, platform_device_register_* helpers assign
DMA_BIT_MASK(32) dma_mask to the platform devices it registers. It is
unnecessary to define it explicitly in struct platform_device_info
hence, drop this explicit dma_mask assignment.

This will help simplying the vchiq_register_child() going forwards.
No functional changes intended in this patch.
