soc: qcom: llcc: Enable LLCC_WRCACHE at boot on X1

The Last Level Cache is split into many slices, each one of which can
be toggled on or off.

Only certain slices are recommended to be turned on unconditionally,
in order to reach optimal performance/latency/power levels.

Enable WRCACHE on X1 at boot, in accordance with internal
recommendations.

No significant performance difference is expected.
