The Tegra30 EHCI controller is mostly compatible with the Tegra20
controller, except Tegra30 includes the HOSTPC register extension.
The has_hostpc capability bit must be set in the ehci_hcd structure if
the controller has such extensions. The new tegra_ehci_soc_config
structure is added to describe the differences between the SoCs.

Aren't casts from 'const void *' automatic?
