Subject: [PATCH 3/4] regulator: core: Add consumer-requested load in regulator_summary

It's handy to see the load requested by a regulator consumer in the
regulator_summary.  Add it.  Since this patch comes after the patch
("regulator: core: If consumers don't call regulator_set_load() assume
max") we'll also differentiate between the case where a consumer
hasn't called regulator_set_load() and the case where a consumer
called it but the load is currently 0 mA.
