Subject: [PATCH v2 2/2] !!! TESTING ONLY !!! Allow compile virt-dma users on ARM64 platform

This patch is for testing only!

Most of DMA drivers are platform specific and their configuration
options can be enabled only then building kernel for specific
platform. In order to simplify compilation check of such drivers
Kconfig files were modified.
