CONFIG_GPIO does not exist. sysreset_gpio.c uses the DM gpio APIs so the
correct option to select is DM_GPIO.

Improvements and new features:
- split more rockchip pinctrl_core feature into per SoC
- enable TPL for evb-rk3399 board
- enable TPL/SPL for evb-px5 board
- enable TPL and OP-TEE support for evb-rk3229
- update fix in arm common assembly start code for rockchip header file
- update default SPL_FIT_GENERATOR for rockchip
- rk3399 boards update to use '-u-boot.dtsi'
- add new rk3399 boards: Nanopi M4, Nanopc T4
- enable sound for chromebook_minnie

SPL/TPL also need use sysreset for some feature like panic callback.

Add a default implementation of this method which always indicates that
the last reset was a power-on reset. This is the most likely type of reset
and without a PCH-specific driver we cannot determine any other type.

On modern x86 devices we can power the system off using the power-
management features of the PCH. Add an implementation for this.

The EFI implementation of reset sits inside the driver and is called
directly from outside the driver, breaking the normal driver-model
conventions. Worse, it passed NULL as the device pointer, hoping that
the called function won't use it, which breaks as soon as code is added
to use it.

Separate out the implementation to improve the situation enough to allow
a future patch to add new sysreset features.

Rockchip use 'arch-rockchip' instead of arch-$(SOC) as common
header file path, so that we can get the correct path directly.

The sysreset of 'POWER' type is a PMIC reset defined as
'remove and restore power'.
So normally only COLD/WARN is supported by sysreset_syscon.

This modification allows to use the function sysreset_walk(SYSRESET_POWER)
when it is supported by PMIC driver (see example in stpmic1).

Use the new function syscon_regmap_lookup_by_phandle()
to simplify the code.

Our selftest will soon test the actual runtime reset function rather than
the boot time one. For this, we need to ensure that the runtime version
actually succeeds on x86 to keep our travis tests work.

So this patch implements an x86 runtime reset function. It is missing
shutdown functionality today, but OSs usually implement that via ACPI
and this function does more than the stub from before, so it's at least
an improvement.

Eventually we will want to have full DM functionality in runtime services.
But this fixes a travis failure and doesn't clutter the code too heavily, so
we should pull it in without the amazing new RTS DM framework.
