regulator: Allow boot_on regulators to be disabled by clients
Rather than incrementing the reference count for boot_on regulators (which prevents them being disabled later on) simply force the regulator to be enabled when applying the constraints. Previously boot_on was essentially equivalent to always_on. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Liam Girdwood <lrg@slimlogic.co.uk>
