ARM: dts: qcom: msm8226-motorola-falcon: limit TPS65132 to 5.4V

Browse Source 
After some digging in downstream sources, it was found that the TPS65132
outputs are fixed to +5.4V and -5.4V respectively. This is further confirmed
on runtime through debugfs, the troubleshooting guide confirms this as well.
Specify these limits as such.
