pci: msm: Enable or disable GDSC PHY regulator only when gdsc_phy exits

Browse Source 
In some targets like sdxbaagha only GDSC core exits and no separate
GDSC phy is used.
So we need to make sure that enabling or disabling the regulator for
GDSC phy is only when gdsc-phy node exits in device tree.
