[U-Boot] [PATCH 1/1] blk: set log2blksz in blk_create_device()

[Heinrich Schuchardt]

The ext4 file system requires log2blksz to be set. So when setting the
block size on the block descriptor we should fill this field too.

This fixes a problem with EFI block devices providing ext4 partitions, cf.
