[msm7x30] Check local clock control state and enable hsusb clocks
In order to be compatible with modem versions that do not always grant
local clock control for usb to apps processor, we check the status
of hsusb core clock local clock control. If we have local clock
control, we enable it ourselves using shadow register. If not, then
make a proc comm to modem to enable the same.
Also included minor cleanup to move usb clock initializations to
platform specific area.
