Revert "ARM: dts: qcom: enable ICE driver for msm8994"

ICE (Inline Crypto Engine) support requires Key restoration after
UFS power collapse. This operation adds long latency to exit from
power collapse and will impact the performance even when ICE is
not in use.

This reverts commit 56cab451 and ICE
will be enabled only on products that requires data encryption.
