ARM: dts: msm: Update QoS values for sdm670
Different devices like usb, gpu, sde, sdhc and ufs uses different
QoS values. Based on exit latencies on sdm670, these all values
are blocking deeper LPMs and allows only WFI mode.
For scenarios where one request is already active that allow only WFI
mode LPM and new request is added that also allows only WFI mode but
the value is different.
For such cases QoS framework still notifies cpuidle to wake up CPU from
idle to reselect new mode based on new aggregated QoS value.
Update QoS values to same (WFI exit latency + 1) for all devices blocking
same LPM mode to avoid such wake ups.
