[v6,2/2] arm64: dts: qcom: add SA8540P ride(Qdrive-3)

  Introduce the Qualcomm SA8540P ride automotive platform, also known as
Qdrive-3 development board.

This initial contribution supports SMP, CPUFreq, cluster idle, UFS, RPMh
regulators, debug UART, PMICs, remoteprocs and USB.

The SA8540P ride contains four PM8450 PMICs.

Not sure if setting load is desired after recent rpmh regulator changes.

Please add a pm8450[aceg].dtsi instead, as other boards would probably 
like to
reuse this. Also, move the spmi.h inclusion there.

Not sure if it's useful if there's nothing there for now.

With Konrad's requested changes:

Reviewed-by: Brian Masney <bmasney@redhat.com>
Tested-by: Brian Masney <bmasney@redhat.com>

After more research, I've verified that the board reboot issue that
I brought up in v5 is unrelated to the DTS, so no need to block merging
this. I'll post some more findings soon about the issue.

May I know the exact patch being refered here?

Hi Parikshit,

You now need to specify a regulator-allowed-modes. Here's some links
with more information:

As we don't have ufs_card_hc for ride platform, we can remove vreg_l3c.

Similarly we can remove this vreg_l10c.
