msm: ipa: SDM660 miscellaneous changes 



Add support to Enable/Disable uc monitor holb feature.

sdm660 does not  support uc monitor holb feature.
Make changes to get this param via device tree to
support devices which handle holb monitoring via IPA uC.

sdm660 supports WLAN offload. Make changes to configure
wlan pipes on IPA2.6L needed to support WLAN offload.
