usb: rockchip: implement K_FW_LBA_READ_10 command

Browse Source 
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.
