phy: amlogic: phy-meson-gxl-usb2: rename some of the U2P_R2 registers
The U2P_R2 register provides "test mode" functionality for bits 17:0. These are only used during SoC development and should be left untouched on production SoC versions. Rename these register definitions to indicate that these are for "test mode" only. While here, also merge the definitions for U2P_R2_DATA_IN_MASK and U2P_R2_DATA_IN_EN_MASK (bits 0:7) because Amlogic's internal documentation suggests that these bits belong together. The old definition was not taken from the documentation but rather from a struct definition in the Amlogic GPL kernel sources. No functional changes.
