[PATCH 2/2] MIPS: add readl/write_be

[Florian Fainelli <ffainelli@freebox.fr>]

MIPS currently lacks the readl_be and writel_be accessors
which are required by BCM63xx for OHCI and EHCI support.
Let's define them globally for MIPS. This also fixes the
compilation of the bcm63xx defconfig against USB.
