pc-bios/s390-ccw: support all virtio block size
The block size value may be given "as is" OR as a base value and
a shift count (exponent). So, we have to use calculation to get
the proper number in the code.
The main expression reads as
(blk_cfg.blk_size << blk_cfg.physical_block_exp)
E.g., various combinations between blk_size=1/physical_block_exp=12
and blk_size=4096/physical_block_exp=0 are valid for 4K blocks.
