Adds SM501 usb host emulation feature.
It makes usb keyboard available for sh4/r2d system emulation. The changes for "hw/usb-ohci.c" are as follows. - 'localmem_base' is introduced as OHCIState struct member. SM501 has a local memory, and it is used to pass and receive data with OHCI driver. OHCI driver accesses it with SH4 physical memory address, and SM501 accesses it with SM501 local address. 'localmem_base' holds where the SM501 local memory is mapped into SH4 physical address space. - Memory access functions modified to adjust address with 'localmem_base'. The functions are, ohci_read_*(), ohci_put_*(), and ohci_copy_*(). - ohci_read_hcca() and ohci_put_hcca() are introduced for more consistent implementation. For other source files, it does, - introduces usb_ohci_init_sm501(). - adds irq argument for SM501 initialization, to emulate USB interrupts.
