regulator: core: Let boot-on regulators be powered off

Browse Source 
commit 089b3f61ecfc43ca4ea26d595e1d31ead6de3f7b upstream.

Boot-on regulators are always kept on because their use_count value
is now incremented at boot time and never cleaned.

Only increment count value for alway-on regulators.
regulator_late_cleanup() is now able to power off boot-on regulators
when unused.

Fixes: 05f224ca6693 ("regulator: core: Clean enabling always-on regulators + their supplies")
