nand: extend nand torture
nand torture currently works on exactly one nand block which is specified
by giving the byteoffset to the beginning of the block.
Extend this by allowing for a second parameter specifying the byte size
to be tested.
e.g.
==> nand torture 1000000
NAND torture: device 0 offset 0x1000000 size 0x20000 (block size 0x20000)
Passed: 1, failed: 0
==> nand torture 1000000 40000
NAND torture: device 0 offset 0x1000000 size 0x40000 (block size 0x20000)
Passed: 2, failed: 0

[scottwood: fix usage to show size as optional, and add misssing braces]
