Andreas Dannenberg 694b052401 sysreset: Add TI System Control Interface (TI SCI) sysreset driver
Devices from the TI K3 family of SoCs like the AM654x contain a Device
Management and Security Controller (SYSFW) that manages the low-level
device control (like clocks, resets etc) for the various hardware
modules present on the SoC. These device control operations are provided
to the host processor OS through a communication protocol called the TI
System Control Interface (TI SCI) protocol.

This patch adds a system reset driver that communicates to the system
controller over the TI SCI protocol for allowing to perform a system-
wide SoC reset.

Enable system reset drivers which can be used to reset the CPU or
board. Each driver can provide a reset method which will be called
to effect a reset. The uclass will try all available drivers when
reset_walk() is called.

Reset support via GPIO pin connected reset logic. This is used for
example on Microblaze where reset logic can be controlled via GPIO
pin which triggers cpu reset.
