	pc-bios/s390-ccw: handle more ECKD DASD block sizes
		
			
			Using dasdfmt(8) to format a DASD allows to choose a block size. There are four supported values: 512, 1024, 2048, and 4096 bytes per block. Each block size leads to selection of new count of sectors per track. The head count remains always the same: 15. This empiric knowledge is used to detect ECKD DASD to IPL from.
