The RZ/G2L SMARC module is powered via a Renesas RAA215300 PMIC which
provides several voltage converters, a real time clock (RTC) and reset
control. A basic driver is implemented for this device so that we can
read, write and dump the PMIC registers.
The raa215300_bind() function is added as a stub, binding of the
sysreset driver will be added in a later patch.
Additional features of this PMIC (such as reset control) may be
supported by future patches.

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 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.

For Rockchip boards with the all rk8xx series PMICs (excluding the
rk808), it is sometimes desirable to not boot whenever the device is
plugged in. An example would be for the Odroid Go Advance.
This provides a configurable option to check the PMIC says it was
powered because of a plug-in event. If the value is 1 and this option
is selected, the device shuts down shortly after printing a message
to console stating the reason why it's shutting down. Powering up the
board with the power button is not affected.
This patch parallels the work done in the following patch series:

LDO5 has two separate control registers. LDO5CTRL_L is used if the
input signal SD_VSEL is low and LDO5CTRL_H if it is high.
The current driver implementation only uses LDO5CTRL_H. To make this
work on boards that have SD_VSEL connected to a GPIO, we add support
for specifying an optional GPIO and setting it to high at probe time.
In the future we might also want to add support for boards that have
SD_VSEL set to a fixed low level. In this case we need to change the
driver to be able to use the LDO5CTRL_L register.
This is a port of the same change in the Linux kernel:
