Subject: [PATCH v3 2/4] arm64: dts: qcom: ipq6018: add 1.5GHz CPU Frequency

The IPQ6005 SoCs and some IPQ6000 SoCs (with PMIC, no fused)[1] have
CPU frequencies up to 1.5GHz, so add this frequency.

[1] Usually the SBL version is BOOT.XF.0.3-00077-IPQ60xxLZB-2
The old version of IPQ6000 did not explicitly fused the SoC to
be 'IPQ6000', and fused the CPU frequency to 1.5GHz.
