[igt-dev] [PATCH i-g-t v8 10/15] lib/xe_ioctl: update vm_bind to account for pat_index

[Matthew Auld]

Keep things minimal and select the 1way+ by default on all platforms.
Other users can use intel_buf, get_offset_pat_index etc or use
__xe_vm_bind() directly.  Display tests don't directly use this
interface.
