[PATCH 06/10] mtd-utils: nandwrite: Use 64-bit offset

[Brian Norris]

To support large NAND devices, we need 64-bit data types for
write offsets. This patch makes data type changes along with
their corresponding printf() formats and the input conversion
(i.e., use "strtoll()" instead of "strol()").
