mtd: Update internal API to support 64-bit device size
MTD internal API presently uses 32-bit values to represent device
size. This patch updates them to 64-bits but leaves the external API
unchanged.
In general, changing from 32-bit to 64-bit values cause little
or no changes to the majority of the code with the following
exceptions:
- printk message formats;
- division and modulus of 64-bit values (mtd_div_by_wb,
mtd_div_by_eb may be used in some of such cases).
Was tested on phyFLEX i.MX6.
