This should map the whole GENERAL area of the SCM register space instead
in one or multiple sections or driver instances. This way the same driver
can be used for the misc SCM registers from other drivers.

If you don't define it that way now, you'll end up with broken child driver
offsets in the .dts files later on.

Then the pbias_regulator needs to have the standard reg property as an
offset from the SCM GENERAL base address.
