part/dev_desc: Add log2 of blocksize to block_dev_desc data struct
log2 of the device block size serves as the shift value used to calculate the block number to read in file systems when implementing avaiable block sizes. It is needed quite often in file systems thus it is pre-calculated and stored in the block device descriptor. Signed-off-by: Egbert Eich <eich@suse.com>
