USB: PHY: JZ4770: Unify code style and simplify code.
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.
