1. EEPROM: move eepromInUse and eepromSize from EepromReset() to eepromInit()
to avoid re-initializing during a reset (makes item below redundant)
2. Remove gbaSaveType variable - this is now redundant due to change above
which probably was added for this reason since games using eeprom fails with
gamepak error after a reset.
3. Add labels to identify cpuSaveTypes
4. libretro: remove workaround for eeprom reset issue (#1), do not apply
custom gbPalettes if not running in GB, change vram size to 0x18000 in
memory map
For the most part, save types should now be identified during rom loading and then allow libretro to correctly use flash or eeprom save types and save size.
