block: Add driver methods to probe blocksizes and geometry
Introduce driver methods of defining disk blocksizes (physical and
logical) and hard drive geometry.
Methods are only implemented for "host_device". For "raw" devices
driver calls child's method.
For now geometry detection will only work for DASD devices. To check
that a local check_for_dasd function was introduced. It calls BIODASDINFO2
ioctl and returns its rc.
Blocksizes detection function will probe sizes for DASD devices.
