dm: core: Fix address translation in devfdt_get_addr_index()
During address translation #address/size-cells props are expected to
apply to child nodes. However, devfdt_get_addr_index() incorrectly use
the parent offset of the udevice parent instead of getting the offset of
the node parent. This will work in most cases when there is only one
udevice tied to a node.
On e.g. an Orange Pi R1 Plus TLS board the dwc3-generic (parent) and
dwc3-generic-host (child) udevice is tied to the same node.
In that case both the offset and parent values end up being the same.
As a result, the #address/size-cells props intended for child nodes
incorrectly gets applied to the node itself resulting in wrong addr
being returned, 0x0 instead of 0xff600000.
The following can be seen on console:
dwc3-generic-host usb@ff600000: this is not a DesignWare USB3 DRD Core
dwc3-generic-host usb@ff600000: failed to initialize core
Fix this by using the offset of the parent node and not the offset to
the node the parent udevice is tied to.

Historically, Qualcomm boards have relied on heavy hardcoding in U-Boot,
in many cases to the specific SoC but also to the board itself (e.g.
memory map). This has been largely resolved by modernising the Qualcomm
drivers in U-Boot, however the board code still largely follows this
model.
This patch removes the board specific memory maps and duplicated board
init code, replacing it with generic init code.
The memory map is now built at runtime based on data read from DT, this
allows for the memory map to be provided without having to recompile
U-Boot. Support is also added for booting with appended DTBs, so that
the first-stage bootloader can populate the memory map for us.
The sdm845 specific init code is dropped entirely, it set an environment
variable depending on if a button was pressed, but this variable wasn't
used in U-Boot, and could be written to use the button command instead.
The KASLR detection is also dropped as with appended dtb, the kaslr seed
can be read directly from the DTB passed to U-Boot.
A new qcom_defconfig is added, with the aim of providing a generic
U-Boot configuration that will work on as many Qualcomm boards as
possible. It replaces the defconfig files for the Dragonboard 845c,
Galaxy S9, and QCS404 EVB. For now the db410c and 820c are excluded as
they still have some board code left.
Similarly, the config headers for db845c, starqltechn, and qcs404-evb

The previously db410c-specific board_usb_init() function is made to be
generic and is added to mach-snapdragon. While we lack proper modelling

gpio: qcom_pmic: add pinctrl driver
Introduce a basic pinctrl driver for the SPMI PMIC GPIOs. This is
necessary to make proper use of upstream DT bindings specifically on the
dragonboard410c where they're used to switch between USB host and device
modes.
Only support for driving the pins as output low or high is enabled for
now.
To minimise duplicated code and allow for sharing common DT data, the
pinctrl driver is initialised as a child of the existing GPIO driver.

gpio: qcom_pmic: add a quirk to skip GPIO configuration
Some platforms hard reset when attempting to configure PMIC GPIOs. Add
support for quirks specified in match data with a single quirk to skip
this configuration. We rely on the GPIO already be configured correctly,
which is always the case for volume up (the only current user of these
GPIOs).
This is not expected behaviour but appears to be due to a U-Boot
specific bug. This quirk at least allows for the volume buttons to be
used on platforms where this bug is apparent.

serial: msm: fix clock handling and pinctrl
Use the modern helpers to fetch the clock and use the correct property
("clocks" instead of "clock"). Drop the call to pinctrl_select_state()
as no boards have a "uart" pinctrl state and this prints confusing
errors.

serial: msm: add debug UART
Introduce support for early debugging. This relies on the previous stage
bootloader to initialise the UART clocks, when running with U-Boot as
the primary bootloader this feature doesn't work. It will require a way
to configure the clocks before the driver model is available.

usb: dwc3-generic: support external vbus regulator
Add support for a vbus-supply regulator specified in devicetree. This
provides generic support to avoid hardcoded GPIO configuration in board
init code.
