Upstream commit 2e01e0c21459 ("arm64: dts: qcom: sdm850-yoga:
Enable IPA") shuffled reserved memory regions in sdm845.dtsi
to make firmware loading succeed and enable the ipa device on
sdm845-yoga but it broke the other common users of those
memory regions like Xiaomi Pocophone F1.
So this patch effectively revert those upstream commit changes
and move all the relevant changes to sdm850-lenovo-yoga-c630.dts
instead.
Fixes: 2e01e0c21459 ("arm64: dts: qcom: sdm850-yoga: Enable IPA")

Tested on the Lenovo Yoga C630 I have. I get the ipa modem device, so it looks like it does the correct thing. I don't have a SIM card to test actual connectivity though.

Thanks for the report and fix Amit, I verified that this works fine on
my Yoga as well.
