ENGR00174540: i.mx6: anatop_regulator: LDO voltage print not correctly

The LDO voltage constraint not printed correctly:

print_constraints: vddpu: 725 <--> 1300 mV at 700 mV fast normal
print_constraints: vddsoc: 725 <--> 1300 mV at 700 mV fast normal
print_constraints: vdd2p5: 2000 <--> 2775 mV at 2000 mV fast normal
print_constraints: vdd1p1: 800 <--> 1400 mV at 700 mV fast normal
print_constraints: vdd3p0: 2800 <--> 3150 mV at 2625 mV fast normal

There due to one typo: << in the code, thus will make the LDO constraint print
not correctly, the patch will make the print correctly as the followings:

print_constraints: vddpu: 725 <--> 1300 mV at 1100 mV fast normal
print_constraints: vddsoc: 725 <--> 1300 mV at 1200 mV fast normal
print_constraints: vdd2p5: 2000 <--> 2775 mV at 2400 mV fast normal
print_constraints: vdd1p1: 800 <--> 1400 mV at 1100 mV fast normal
print_constraints: vdd3p0: 2800 <--> 3150 mV at 3000 mV fast normal
