phy: exynos5-usbdrd: convert some FIELD_PREP_CONST() to FIELD_PREP()

Use of FIELD_PREP_CONST() was a thinko - it's meant to be used for
(constant) initialisers, not constant values.

Use FIELD_PREP() where possible. It has better error checking and is
therefore the preferred macro to use in those cases.
