atheros: update macroses names

Browse source 
Use AR2315_ prefix for macroses specific to AR2315/AR2316/AR2317 chips,
use AR5312_ prefix for macroses specific to AR5312/AR2312/AR2313 chips,
and use AR231X_ prefix for common macroses.

This patch should not cause any functional changes, only make clear
which macros is common and which macros is specific.
