ARM: dts: msm: Add HSPHY CSR registers and workaround to MSM8994 



These additional CSR registers are needed to place the USB HS
Pico PHY into deep low power state when the cable is removed.

Also enable the workaround to keep the analog LDOs enabled
during suspend in order to prevent leakage through the PHY.
