ENGR00241003-1 mx6: need to add delay in LDO voltage setting
1.LDO ramp up time may be modified by ROM code according to fuse setting, cpu freq driver use fixed delay time which assume the LDO ramp up time is the reset value of ANATOP register, need to set it to reset value in regulator init. 2.The regulator set voltage should take care of the ramp up time, calculate the ramp up time based of register setting and to the delay, make sure that when the set voltage function return, the voltage is stable enough. 3.CPUFreq no need to use delay, it is already taken care by regulator voltage setting.
