Subject: [PATCH v2 1/7] virtio-gpu api: add HSAKMT context

From: Honglei Huang <Honglei1.Huang@....com>

Add a new context named HSAKMT for compute use case.

- The capset VIRTIO_GPU_CAPSET_HSAKMT used for context init,
in this series patches only HSAKMT context can use the userptr
feature. HSAKMT is a GPU compute library in HSA stack, like
the role libdrm in mesa stack.
