Linux DTs stuff a value indicating if the USID is a USID or a GSID in the
reg property, the Linux SPMI driver then reads the two address cells
separately. U-boot's dev_read_addr() doesn't know how to handle this, so
use ofnode_read_u32_index() to get just the USID.
The Qcom pmic driver doesn't have support for GSID handling, so just
ignore the second value for now.

The original H616 devices released about three years ago were typically
paired with an X-Powers AXP305 PMIC. Newer devices uses the smaller
AXP313, and there seem to be far more systems with this PMIC around now.
Remove the default AXP305 selection for the H616 SoC from the Kconfig,
and move the PMIC selection into the board defconfig files instead.

On boards using the AXP313 PMIC, the DRAM rail is often not setup
correctly at reset time, so we have to program the PMIC very early in
the SPL, before running the DRAM initialisation.
Add a simple AXP313 PMIC driver that knows about DCDC2(CPU) and
DCDC3(DRAM), so that we can bump up the voltage before the DRAM init.

So far we have a convoluted #ifdef mesh that guards the early AXP PMIC
setup in board.c. That combination of &&, || and negations is very hard
to read, maintain and especially to extend.
Fortunately we have those same conditions already modelled in the
Kconfig file, so they are actually redundant. On top of that the real
reason we have those preprocessor guards in the first place is about the
symbols that are *conditionally* defined: without #ifdefs the build
would break because of them being undefined for many boards.
To simplify this, just change the guards to actually look at the symbols
needed, so CONFIG_AXP_xxx_VOLT instead of CONFIG_AXPyyy_POWER.
This drastically improves the readability of this code, and makes adding
PMIC support a pure Kconfig matter.
Doing this revealed one bug in Kconfig: there is no axp_set_dcdc4() for
the AXP818, even though CONFIG_AXP_DCDC4_VOLT includes that PMIC.
Since the AXP818 wasn't included when calling axp_set_dcdc4() in board.c,
this wasn't an issue, but becomes one now, so also remove the AXP818 from
the DCDC4 Kconfig symbol.

The commit 30975fb73d ("rockchip: Add option to prevent booting on
power plug-in") introduce an option to prevent booting a device when the
device was powered on due to power plug-in instead of pressing a power
button.
This feature works by checking the power-on source during PMIC probe
and powers off the device if power-on source was power plug-in.
This check currently runs very late at PMIC probe in U-Boot proper.
Fix so that the power-on source check can work at probe time in SPL.
Also enable probe after bind and remove the PMIC banner in SPL.
With this we can use ROCKCHIP_RK8XX_DISABLE_BOOT_ON_POWERON and
SPL_PMIC_RK8XX to power off the device very quickly after TPL instead
of after TF-A and U-Boot proper has been loaded and run.
