The AXP209 supports ramping up voltages on several regulators such as DCDC2 and LDO3. This patch adds preliminary support for the regulator-ramp-delay property for these 2 regulators. Note that the voltage ramp only works when regulator is already enabled. E.g. when going from say 0.7 V to 3.6 V. When turning on the regulator, no voltage ramp is performed in hardware. What this means, is that if the bootloader brings up the voltage at 0.7 V, the ramp delay property is properly applied. If however, the bootloader leaves the power off, no ramp delay is applied when the power is enabled by the regulator framework. Signed-off-by:
