regulator: db8500-prcmu: Separate regulator registration from probe
This will provide us with a convenient way to register regulators when booting with Device Tree both enabled & disabled and will save us a great deal of code duplication in time. Signed-off-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
