Details:
For Xmega devices, data memory mapping of the EEPROM section can be enabled by
setting EEPROM Data Memory Mapping Enable bit (EEMAPEN). This allows us to
load/store EEPROM using load/store instructions.
But for Xmega E series, EEPROM is memory mapped in the data memory by default.
Data addresses 0x1000 to 0x1FFF are reserved for EEPROM.
So, setting EEMAPEN bit is not required for Xmega E series devices.
This patch modifies eeprom read/write functions to do memory map only if
EEMAPEN bit exists.
