Revert "arm64: dts: qcom: msm8996: add missing TCSR syscon compatible"

This reverts commit 8a99e0fc ("arm64: dts: qcom: msm8996: add
missing TCSR syscon compatible").

This commit marked the saw3 (syscon@9a10000) node as compatible with
qcom,tcsr-msm8996. However the mentioned device is not not a TCSR
(system registers, hardware mutex). It is a CPU power
controller/regulator, which is currently being handled as a syscon.
