m25p80: change cur_addr to 32 bit integer
The maximum amount of storage that can be addressed by the m25p80 command
set is 4 GiB. However, cur_addr is currently a 64-bit integer. To avoid
further problems related to sign extension of signed 32-bit integer
expressions, change cur_addr to a 32 bit integer. Preserve migration
format by adding a dummy 4-byte field in place of the (big-endian)
high four bytes in the formerly 64-bit cur_addr field.
