arm/dt: msm8974: Use voltage floor corner for PM8841 SMPS 2 and SMPS 4

Add voltage floor corner regulator interfaces in the MSM8974
device tree for the PM8841 SMPS 2 and SMPS 4 regulators (VDD_CX
and VDD_GFX respectively).  These interfaces will be used to
impose a minimum active voltage corner in low temperature
situations.
