This patch implement reading blocks form selected device with LBA addressing.
Corresponding command on workstation is: rkdeveloptool rl <start_blk> <blk_cnt> <file>
While we support reading more than one blocks per K_FW_LBA_READ_10 request, rkdeveloptool and original rockchip tool do perform chunk reads limiting the maximum size per chunk far lower than max int values.
