[RFC PATCH 02/11] powerpc/svm: Select CONFIG_DMA_DIRECT_OPS and CONFIG_SWIOTLB

[Thiago Jung Bauermann <bauerman@linux.ibm.com>]

From: Anshuman Khandual <khandual@linux.vnet.ibm.com>

Ultravisor based secure guest platforms will use generic SWIOTLB DMA API
(i.e swiotlb_dma_ops structure) available under the CONFIG_DMA_DIRECT_OPS
config. Also base CONFIG_SWIOTLB needs to be explicitly selected as well.
Select both these config options on powerpc server platforms with secure
guest support.
