ehci-ppc4xx: Prepare for usage of readl()/writel() accessors

We used to have opencoded ehci_readl()/writel() which required no
external functions to be called.

Now with attempt to switch to generic readl()/writel() accessors
we see a missing declaration of those accessors in ehci-ppc4xx.
Something like that happens if applied
