ufs: qcom: add dts property to disable LPM modes
Since msmcobalt RUMI uses QRBTC-V2 UFS PHY, there are a few limitations
that must be applied in order to be able to initialize UFS:
1. UFS should remain in PWM-G1 1-Lane and never change its gear, as other
gears are not stable
2. hibern8 enter/exit should be bypassed
3. we should avoid any power change (as in runtime suspend/resume)
Add "qcom,disable-lpm" property to facilitate disabling of these.
