This can be done as a preparatory patch if we decide to do it this way,
for the review it seemed better to spell out that this is required.

I still hope that we can avoid adding another 'select RESET_CONTROLLER'
if someone can figure out what to do instead.

The problem here is that QCOM_SCM selects RESET_CONTROLLER,
and turning that into 'depends on' would in turn mean that any driver that
wants to select QCOM_SCM would have to have the same RESET_CONTROLLER

An easier option might be to find a way to build QCOM_SCM without
RESET_CONTROLLER for compile testing purposes. I don't know
what would break from that.
