usb: write command for RAW partition.
This patch implements write support to usb device with raw partition.
It will be useful for filesystem write support to usb device from
u-boot in future.
Tested with writing kernel image to raw usb disk & booting with usb
read command into ram.
[Note: run usb part to get info about start sector & number of
sectors on a partition for usb write operation.]
