ehci: Fix resource size
We now have a resource size for the ehci hccr register space. This
was assumed to be 0x40 in size. On OMAP though it is only 0x10 and
then the hccr resource conflicts with the hcor resource which results
in a non working ehci port on beagle and panda boards. This patch
adds a nonintrusive workaround, it limits the hccr resource to 0x10,
which then also works on OMAP.
Later we should drop the multiple resources for the ehci port and
make the resource as specified in the datasheets.
This is broken since:
