USB: OHCI: prepare to make ohci-hcd a library module
This patch prepares ohci-hcd for being split up into a core library and separate platform driver modules. A generic ohci_hc_driver structure is created, containing all the "standard" values, and a new mechanism is added whereby a driver module can specify a set of overrides to those values. In addition the ohci_restart(),ohci_suspend() and ohci_resume() routines need to be EXPORTed for use by the drivers. Added ohci_setip(() and ohci_start() routine for to start the generic controller rather than each having its own idiosyncratic approach. This allow to clean duplicated code in most of SOC driver In V2: -ohci_hcd_init() ohci_run() and ohci_stop() are not made non-static. -Adds the ohci_setup() and ohci_start() routine. In V3: -purpose of ohci_setup() and ohci_start() function description written in the patch description. -ohci_init() are not made non-static but now called beginning of the ohci_restart(). -ohci_run() signature change reverted back. -unrelated changes removed. -duplicate comment line removed. -inline ohci_suspend() and ohci_resume() is not needed so removed from ohci.h file. In V4: -ohci-init() EXPORTed because it is called by all bus glue modules. -ohci-setup() removed from 1/2 added into 2/2 patch. In V5: -Again ohci_setup() is added and EXPORTed because to replace the ohci_init() from all bus glues. -ohci_init() is not made non-static function. In V6: -ohci_init() call is removed from ohci_quirk_nec_worker(), because it is already called in ohci_restart(). In V8: -ohci_hcd_init() is called by ohci_setup() to make generic ohci initialization in all ohci drivers.
