Sudeep Holla 61423712db reset: reset-scmi: add missing handle initialisation
scmi_reset_data->handle needs to be initialised at probe, so that it
can be later used to access scmi reset protocol APIs using the same.

Since it was tested with a module that obtained handle elsewhere,
it was missed easily. Add the missing scmi_reset_data->handle
initialisation to fix the issue.

Sudeep Holla c8ae9c2da1 reset: Add support for resets provided by SCMI
On some ARM based systems, a separate Cortex-M based System Control
Processor(SCP) provides the overall power, clock, reset and system
control. System Control and Management Interface(SCMI) Message Protocol
is defined for the communication between the Application Cores(AP)
and the SCP.

Adds support for the resets provided using SCMI protocol for performing
reset management of various devices present on the SoC. Various reset
functionalities are achieved by the means of different ARM SCMI device
operations provided by the ARM SCMI framework.
