These are exactly the same, please just add a comment that the
AXP818 addresses are the same as the AXP223 ones instead
of adding new defines.

And instead of this #elif make the #if above:

#elif defined CONFIG_AXP223_POWER || defined CONFIG_AXP818_POWER

And idem for all the other functions.

Please do not add this AXP818 specific block, instead modify the block below
to work for the 818.
