Don't enable the optee node in the SoC include. It is an optional
component and actually, if enabled, breaks boards which doesn't have it.

This reverts commit 48787485f8de ("arm64: dts: ls1028a: enable optee
node") and enables the node per board, assuming the intend of the
original author was to enable OPTEE for the LS1028A-RDB and the
LS1028A-QDS.

Please disregard this patch, because the offending patch was
already dropped:
https://lore.kernel.org/lkml/20210318084029.GY11246@dragon/

Sahil, if you like you can pick it up to enable the nodes for
your ls1028a boards.

Hi Shawn,

Shall we make this a general rule?  I see quite a few SoC dtsi files
are having the optee node enabled by default.

Leo

Yeah, we should probably make it a general rule considering the issue
reported here.  I thought that optee driver is smart enough to stop
probing if there is no optee os/firmware support found on given platform.
