A number of the Rockchip-specific drivers (IOMMU, display controllers)
are now assuming that CONFIG_PM is set, and may completely misbehave
if that's not the case.

Since there is hardly any reason for this configuration option not
to be selected anyway, let's require it (in the same way Tegra already
does).

Identify the SoC type and revision, and register this information with
the SoC bus, so it is available under /sys/devices/soc0/, and can be
checked where needed using soc_device_match().

Identification is done using the Product Register or Common Chip Code
Register, as declared in DT (PRR only for now), or using a hardcoded
fallback if missing.

Example:

While debugging a kernel image size issue, I discovered that if all
non ARCH_QCOM configs in the ARM64 defconfig are disabled, the QCOM
pinctrl drivers will not be built.

The QCOM pinctrl drivers have a dependency on GPIOLIB which was being
selected when other ARCH configs were enabled, but ARCH_QCOM doesn't
select GPIOLIB directly.  Let's select GPIOLIB here to ensure the pinctrl
drivers are built for QCOM platforms.

The pinctrl driver is essential for the Allwinner SoCs to work.
Add the driver's config symbol to the Kconfig entry to always compile
it in. We can't use the arm approach to make the _driver's_ Kconfig
symbol def_bool, because we lack the MACH_* symbols in arm64.
That line was in the original pinctrl driver patch, but got removed
to avoid the dependency on the Kconfig patch [1].
Also add the general PINCTRL symbol, which isn't selected automatically
for the same reason.
