The commit 2a6c0b82e651 ("USB: PHY: JZ4770: Add support for new
Ingenic SoCs.") introduced the initialization function for different
chips, but left the relevant code involved in the resetting process
in the original function, resulting in uninitialized variable calls.

Fixes: 2a6c0b82e651 ("USB: PHY: JZ4770: Add support for new Ingenic SoCs.").
