As a general rule of thumb we do not set default-triggers for
sunxi boards in the kernel.

Since you specify this as simplefb supply I do not think
you need always-on here.

Since we do not have a csi driver yet marking these 2
always-on seems unnecessary. Once we get a csi driver
they should get turned on by this driver when
necessary.
