Some of the db410c board support code was written to be generic and
placed in mach-snapdragon. However, as the db410c is the only board
using this, move the code out of mach-snapdragon. This makes is more
obvious what code is relevant for which targets and helps tidy things up
a little more.
Use the root compatible strings from upstream Linux, add missing
'#clock-cells' property to the gcc node.
Adjust some of the msm8916/apq8016 drivers to use the correct upstream
compatible properties and DT bindings.
This prepares us to switch to upstream DT in a future patch.

On the DB410c we support running as a first stage bootloader. This
requires initialising the GPIOs which are muxed to UART before they can
be used. Add DM_FLAG_PRE_RELOC to the apq8016 pinctrl driver to ensure
that we do this early enough.
This is required to prevent the first few lines of UART
Upstream devicetrees label GPIOs with "gpioX", not "GPIO_X", fix this

Most platforms have a handful of "special" GPIOs, like the MMC
clock/data lanes, UFS reset, etc. These don't follow the usual naming
scheme of "gpioX" and also have unique capabilities and registers. We
can get away without supporting them all for now, but DT compatibility
is still an issue.

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.
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).
Qualcomm PMICs number their GPIOs starting from 1, implement a custom
.xlate method to handle this.

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.

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.
