The Intel Edison OTA process requires a conversion of data size
from bytes to number of blocks. The following functions are used:

# function ota_conv_sizes
# Convert a bytes size to a block size
# input bytesize : size in bytes to convert
# input blksize : size of a block in bytes
# output num_blk : converted size in blocks

# function ota_mmc_write
# Write a memory buffer to mmc drive
# input floadaddr : address of buffer to write
# input u_part_start : block start in mmc
# input num_blk : number of block to write

This patch adds the cmd part sub-command 'block' which returns
the partition block size in bytes.
