ENGR00139213: Add read and change voltage support for mx6

dd read and change voltage support for mx6.
For help, pls type "help regul"
Detail command info:
regul list - List all regulators' name
regul show all - Display all regulators' voltage
regul show core - Show core voltage in mV
regul show periph - Show peripheral voltage in mV
regul show <regulator name> - Show regulator's voltage in mV
regul set core <voltage value> - Set core voltage in mV
regul set periph <voltage value> - Set periph voltage in mV
regul set <regulator name> <voltage value> - Set regulator's voltage in
mV

Example:
MX6Q ARM2 U-Boot > regul list
Name            Voltage
vddpu
vddcore
vddsoc
vdd2p5
vdd1p1
vdd3p0
MX6Q ARM2 U-Boot > regul show all
Name            Voltage
vddpu           1100000
vddcore         1100000
vddsoc          1200000
vdd2p5          2400000
vdd1p1          1100000
vdd3p0          3000000
MX6Q ARM2 U-Boot > regul show periph
Name            Voltage
periph:         1100000
MX6Q ARM2 U-Boot > regul show core
Name            Voltage
core:           1100000
MX6Q ARM2 U-Boot > regul set core 1100000
Set voltage succeed!
Name            Voltage
core:           1100000
