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
http://patchwork.ozlabs.org/patch/726714/:
---------------->8---------------
  CC      drivers/usb/host/ehci-ppc4xx.o
drivers/usb/host/ehci-ppc4xx.c: In function 'ehci_hcd_init':
drivers/usb/host/ehci-ppc4xx.c:23:3: warning: implicit declaration of function 'readl' [-Wimplicit-function-declaration]
   HC_LENGTH(ehci_readl(&(*hccr)->cr_capbase)));
   ^
