Subject: [PATCH] arm64: dts: qcom: Add Google Herobrine WIFI SKU dts fragment
The Google Herobrine WIFI SKU can save 256M by not having modem/mba/rmtfs
memory regions defined. Add the dts fragment and mark all the board files
appropriately.
Signed-off-by: Sibi Sankar <quic_sibis@...cinc.com>

Depends on:
Add LTE SKUs for Villager: https://patchwork.kernel.org/project/linux-arm-msm/cover/20220830182923.3720287-1-dianders@chromium.org/
Instead of just having remoteproc_mpss node disabled, we go ahead and
delete it on wifi only SKUs. This is done to avoid the dtbs_check
failures that we would end of getting if we delete the memory-region
property present in the node (since it's a required property). I'll
send a follow up patch with IPA node enabled only on LTE SKUs as soon
as I verify that it doesn't have any affects on suspend/resume.
