than wrote.

e11f9166f3 usb: rockchip: implement K_FW_LBA_READ_10 command
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.

e4b34a7634 usb: rockchip: implement skeleton for K_FW_GET_CHIP_VER command
Chip Version is a string saved in BOOTROM address space Little Endian.

Ex for rk3288: 0x33323041 0x32303134 0x30383133 0x56323030
which brings:  320A20140813V200

Note that memory version do invert MSB/LSB so printing the char
buffer would show: A02341023180002V
