Update to latest code from Raspberry Pi github
Detail: Makefile, dwc/* - Updated to latest code from Raspberry Pi github (rev e0001dd59d). Includes the fabled 'FIQ fix' code, although the code isn't yet enabled in the RISC OS version of the driver. c/cmodule - Add extra flags for controlling driver behaviour, as required by the new core code c/dwc_otg_riscos - Add some missing driver parameters (although we leave them at default). Handle DWC_E_SHUTDOWN xfer errors, which will now be produced when the driver is shutting down c/softc_device - Disable interrupts around dwc_otg_hcd_urb_enqueue, to mirror behaviour of Linux code (previously, it was the responsibility of the DWC code to disable interrupts for the appropriate part of the operation) s/regaccess - Add some extra IRQ/memory barrier functions required by the new code (mainly the FIQ fix). Make DWC_MODIFY_REG32 operate atomicly (mirrors change in Linux version) Admin: Tested on Raspberry Pi Version 0.11. Tagged as 'DWCDriver-0_11'
