[PATCH v13 1/4] drm/amdgpu: Allow WIPE_ON_RELEASE to be set on gem create.

[David Francis]

AMDGPU_GEM_CREATE_VRAM_WIPE_ON_RELEASE is a flag that
specifies that gem memory contains sensitive information and
should be cleared  to prevent snooping.

It was meant to be settable in GEM_CREATE_IOCTL but wasn't.

Make a new define AMDGPU_GEM_CREATE_SETTABLE_MASK to
track which gem flags can be used with gem create, and add
wip on release to it.
