Change the minimum mode allowed for L2J from low power mode (LPM) to
retention mode. This can be used to ensure that power is saved once
the secure processor is out of reset.

Configure the L1F and L3G active-only regulator to be always enabled
in high power mode (HPM). These regulators power REFGENs and PLLs
used by the application processor itself. Unconditional active-only
voting is needed since the software running on the application
processor won't be capable of removing L1F and L3G votes after the
application processor subsystem is power collapsed.

Add active-only and sleep-only regulator subnodes for rpmh-regulator
devices L1F and L3G on Sun boards. This allows requests to be issued
for them that are tied to the application processor's power collapse
state.

Configure the L2F and L3F regulators on Sun boards to be always
enabled. This ensures that WCN hardware operates correctly.
Use low power mode (LPM) as the initial mode to reduce current
consumption before BT or WLAN is enabled.

Sun power grid V8 boards have seen a boot-up issue seemingly caused
by device tree overlays not being applied as expected. This results
in the rpmh-regulator-mxlvl device not probing correctly as the
proxy-supply property isn't found/resolved.
Correct this issue by moving regulator phandle creation from V8
overlay DTs into the base DT and not creating any regulator nodes
in the overlay DTs (which are duplicates of ones in the base DT).

Sun boards that utilize the V8 power grid have a PM8550VE PMIC in
place of a PM8550VS one for the "F" PMIC at SPMI SID=5. Several
FTSMPS regulators are ganged together differently and some supplies
are shuffled around. These are the impacts for RPMh managed
regulator resources:
V6 Power Grid V8 Power Grid
S4J WCN_CX XX
S5F XX WCN_CX
S6F VDD_MXA XX
S8F N/A VDD_MXA
Update the device tree configurations for V8-specific overlays so
that the correct set of PMIC resources is present.

The gx_clkctl_gx_gdsc requires both gpu_cc_cx_gdsc and VDD_GX to access
its configuration registers. We access these registers during probe, so
we need to ensure these dependencies aren't disabled until after our
probe completes. Add proxy consumers for this.
After probe, the parent-supply will ensure VDD_GX is enabled before we
touch registers in the regulator_enable/disable paths. And for the CX
GDSC dependency, the client already enables it before the GX GDSC due to
historical functional requirements between the CX and GX sides.
