regulator: dbx500: Make local symbol static
power_state_active_get is used only in this file. Make it static. While at it also move this function definition inside the CONFIG_REGULATOR_DEBUG macro as it is called only from within it. This also avoids further build warning related to unused definition. Signed-off-by: Sachin Kamat <sachin.kamat@linaro.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
