ARM: dts: msm: update wcn3990 wlan device node for APQ8098 



Add clock and regulator nodes for WCN3990.
During recovery, there are cases where in WLAN driver running on
APPS can access CE register causing exceptions because of
hardware in reset state. Fix the issue by not resetting the
hardware in WLAN firmware during recovery but halt the CE and MAC
and reset the hardware only when reinitialization starts. For
this to work, wcn3990 ath10k driver needs to keep the clock and
regulator votes so that WLAN hardware will not go into weird
state because of not resetting it but cutting the resources.
