ARM: dts: msm: Add PDC configuration for WLAN device

Browse Source 
Add configuration data for WLAN Device PMU to Platform VReg mapping,
PDC name to VReg mapping and PDC initialization table for WLAN device.
This is needed to select WLAN device config in multiple device attach
support in platform build.
