USB: Fix EHCI warning
This patch fixes a warning introduced by the big endian MMIO EHCI support patch on platforms that don't have readl_be/writel_be variants (though mostly harmless as those are called in an if (0) statement, but gcc still warns). Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
