add physical_block_size field where applicable

only scsi_disk checks the actual value, other drivers take the logical block size.

This change reports the physical block size from the disk rather than the block
size used by IDE/SATA/SCSI commands. On typical modern SATA disks, the SATA
commands will use 512 byte blocks, but the disk will actually read and write
4K blocks internally. This is only of importance for partition alignment for DriveSetup,
and is independant of file systems or partitioning systems. This could also influence
the recommended block size for some file systems.
