UPSTREAM: reset: add reset controller driver for SCMI agents

This change introduces a reset controller driver for SCMI agent devices.
When SCMI agent and SCMI reset domain drivers are enabled, SCMI agent
binds a reset controller device for each SCMI reset domain protocol
devices enabled in the FDT.

SCMI reset driver is embedded upon CONFIG_RESET_SCMI=y. If enabled,
CONFIG_SCMI_AGENT is also enabled.

SCMI Reset Domain protocol is defined in the SCMI specification [1].

Add Reset Driver for ast2500 SoC. This driver uses Watchdog Timer to
perform resets and thus depends on it. The actual Watchdog device used
needs to be configured in Device Tree using "aspeed,wdt" property, which
must be WDT phandle, for example:

aspeed,wdt = <&wdt1>;
}

reset: implement a driver for the Tegra CAR

Implement a reset uclass driver for the Tegra CAR. This allows clients to
use standard reset APIs on Tegra. This device is intended to be
instantiated by the core Tegra CAR driver, rather than being instantiated
directly from DT. The implementation uses the existing custom Tegra-
specific reset APIs to avoid coupling the series with significant
refactoring of the existing Tegra clock/reset code.

In Tegra186, on-SoC reset signals are manipulated using IPC requests to
the BPMP (Boot and Power Management Processor). This change implements a
driver that does that. It is unconditionally selected by CONFIG_TEGRA186
since virtually any Tegra186 build of U-Boot will need the feature.

Add a reset driver framework/uclass

A reset controller is a hardware module that controls reset signals that
affect other hardware modules or chips.

This patch defines a standard API that connects reset clients (i.e. the
drivers for devices affected by reset signals) to drivers for reset
controllers/providers. Initially, DT is the only supported method for
connecting the two.

The DT binding specification (reset.txt) was taken from Linux kernel
v4.5's Documentation/devicetree/bindings/reset/reset.txt.
