[PATCH] arm64: dts: qcom: sc7180: Make MSA memory fixed for wifi

[Rakesh Pillai]

The MSA memory is at a fixed offset, which will be
a part of reserved memory. Add this flag to indicate
that wifi in sc7180 will use a fixed memory for MSA.

This is not really done for sc7180, but only for the sc7180-idp,
which should be reflected in the subject (i.e. s/sc7180/sc7180-idp/)

Sure Bjorn.
I have sent v2 for the patch "arm64: dts: qcom: sc7180: Add WCN3990 WLAN
module device node", where I have squashed this change as well.

Thanks,
Rakesh.
