EHCI support. All of the credit goes to Aleš Nesrsta. I've just added 

the support for the CS5536 modification thereos and few bugfixes.

	* grub-core/Makefile.core.def (ehci): New module.
	* grub-core/bus/usb/ehci.c: New file.
	* grub-core/bus/usb/usbhub.c (grub_usb_hub_add_dev): New arguments
	port and hubaddr. All users updated.
	Save port and hubaddr into dev structure.
	* include/grub/cs5536.h (GRUB_CS5536_MSR_USB_BASE_SMI_ENABLE): New
	define.
	* include/grub/pci.h (grub_dma_phys2virt): New function.
	(grub_dma_virt2phys): Likewise.
	* include/grub/usb.h (grub_usb_device): New members port and hubaddr.
