Fix the value used for Parallel Transceiver Select (PTS) for the MSM USB
controller. This is a standard chipidea PORTSC definition, where
a PHY_TYPE of 10b (<<30) is ULPI and 11b (<<30) is SERIAL.
Fix the definitions and use them correctly in the driver code.

There could be more than one USB2.0 PHY's on the platform.
This will allow all of them to be registered successfully.

New platform uses RBCPR hardware feature, with that voting for
absolute voltage of VDD CX is not required. Hence vote for corner of
VDD CX which uses nominal corner voltage on VDD CX.

Whether regulators are available or not is checked at driver
probe. If they are not available driver will refuse to load,
so no need to check them again.

Prefix did not bring any useful information. Currently none
of the MSM platforms define these regulators, so it is safe
to rename them.

USB DT bindings states: dr_mode: "...In case this attribute isn't
passed via DT, USB DRD controllers should default to OTG...",
