[PATCH v6 2/5] USB: PHY: JZ4770: Unify code style and simplify code.

["周琰杰 (Zhou Yanjie)" <zhouyanjie@wanyeetech.com>]

1.Modify the macro definition to unify "#define USBPCR_XXXX n"
  into the "#define USBPCR_XXXX (n << USBPCR_XXXX_LSB)" style,
  so as to unify the code style in the "jz4770_phy_init()" and
  simplify the code.
2.Remove unused macro definitions to simplify the code.
