[U-Boot] [PATCH 19/25] eeprom: Pull out CONFIG_SYS_EEPROM_PAGE_WRITE_BITS

Implement default value of 8 for this macro and pull out all of
this macro out of the code. The default value of 8 actually does
implement exactly the same behavior as the previous code which
was in the #else clause of the ifdef.
