[ARM] ohci-pxa27x: introduce flags to avoid direct access to OHCI registers
Direct access to USB host controller registers is considered to be not portable, and is usually a bad sign for poorly abstracted interface. Introduce .flags and .power_on_delay to "struct pxaohci_platform_data" so that most platforms don't bother to write their own .init/.exit() sequences.
