eeprom: at25: Allow page sizes greater than 16 bit
For FRAM devices the page size is usually equal to the device size. Some
available devices are greater than 64kB, so a 32 bit variable must be
used.
The same change has to be done for the Linux driver. I'll try to
upstream this as soon as possible.
