[PATCH v9 2/3] ARM: S3C64XX: Removing old phy setup code

This patch removes old phy code from platform side. 'setup-usb-phy.c'
will be used for providing transceiver platform data in next
patch. Not all of the platform data code is removed as there are others
making use of platform_data defined for hsotg. That can be removed once
all the SoCs start using the new transceiver for usb phy setup.
