arm64: dts: qcom: sdm850-lenovo-yoga-c630: lower PSCI cluster idle

With the default PSCI suspend value for cluster idle state Lenovo Yoga
C630 isn't stable enough. For example it might reset if display device
isn't probed early enough. Drop the bit 0x4000 from the PSCI suspend
value to make C630 work in stable way. The bit was found by
expertimenting with the cluster idle PSCI value. Most likely it results
in the less deep sleep and more energy beign spent in the suspend state,
but it's better than the non-stable system behaviour.
