clk: i.MX7: Fix ethernet clocks

The original clock code from Linux registers some gates at
base + 0x44e0, 0x44f0, 0x4500, 0x4510. These are not in the reference
manual and do not seem to have any effect on the hardware. The
reference manual lists clocks at 0x4700 and 0x4710 which Linux
does not control at all. These clocks really do have an effect on
the hardware and are needed for ethernet support. Register the
existing clocks rather than the made up clocks to support
ethernet.
