phy: qcom-ufs-qmp-14nm: update rx min stall noconfig time
Hibernate entry failures have been observed with some UFS devices.
The UFS PHY Rx termination is not disabled within the specified
RX_Min_STALL_NoConfig_Time_Capability of 15 SI. The UFS device enables
mid-termination after RX_Min_STALL_NoConfig_Time_Capability SI. The
combination of Rx terminated and device Tx mid-termination collapses
the line state to near the differential mid-point. The signal detect
may report the line state incorrectly as DIF-P. The incorrect DIF-P
moves the Rx FSM into the HS-Burst state rather than the intended
Hibern8 state. Fix this issue by setting the UFS PHY's
RX_MIN_STALL_NOCONFIG_TIME_CAPABILITY to 40.
