Once the ethernet clock has been initialized ( set_rate() and clk_enable() ), we need to take
ethernet clock out of reset.

This patch is necessary in this series otherwise U-Boot cannot use ethernet and not able
To boot.

This ethernet reset __prci_ethernet_release_reset() is not depend on SPL or U-Boot proper.
Right now, U-Boot proper is using ethernet so this gets called only for U-Boot proper and if SPL wants
to use ethernet then function helps to take clock out of reset.

I will update the commit description in v10.
