[PATCH] arm64: dts: qcom: Split sdm845-db845c to add headless support

From: Amit Pundir
Date: Mon Jun 05 2023 - 05:47:32 EST

This is a follow-up of the upstream discussion,
https://lore.kernel.org/linux-kernel/20230124182857.1524912-1-amit.pundir@xxxxxxxxxx/T/#u,
around adding a reserved memory region in sdm845-db845c
for the framebuffer memory (the splash region set up by
the bootloader) but the general opinion was to avoid
adding that reserved memory for the headless DB845c
usecase.

So this patch splits the sdm845-db845c into a common dtsi,
a new sdm845-db845-headless DT, which disables the mdss
display subsystem, and a new sdm845-db845c DT with an
additional reserved-memory region for the framebuffer.

The default sdm845-db845c.dtb remains pretty much the same
(with an exception of additional reserved-memory region),
while others can use sdm845-db845c-headless.dtb for their
headless systems.

Please pick this after the lvs regulator nodes reordering patch
https://lore.kernel.org/lkml/20230602161246.1855448-1-amit.pundir@xxxxxxxxxx/T/#u.
I'll rebase and resend this patch otherwise.
