[PATCH -next] reset: reset-scmi: add missing handle initialisation

[Sudeep Holla]

scmi_reset_data->handle needs to be initialised at probe, so that it
can be used to access scmi reset protocol apis using the same later.

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.

Hi Philipp,

I can either take this via ARM SoC as the driver is getting merged through
ARM SoC tree, or you can apply this once it gets landed in mainline.
I am fine with whatever you prefer.

Regards,
Sudeep

Feel free to take this in via ARM SoC directly, I see no need to wait
for this to hit mainline.
