regulator: pca9450: Clear PRESET_EN bit to fix BUCK1/2/3 voltage setting
The driver uses the DVS registers PCA9450_REG_BUCKxOUT_DVS0 to set the voltage for the buck regulators 1, 2 and 3. This has no effect as the PRESET_EN bit is set by default and therefore the preset values are used instead, which are set to 850 mV. To fix this we clear the PRESET_EN bit at time of initialization.
