[PATCH] Add missing $(obj) to aic7xxx makefile

[Vegard Nossum <vegard.nossum@gmail.com>]

Hi,

This patch adds the proper $(obj) and $(src) prefixes to dependency
rules in aic7xxx makefile. Without this patch, there is a remote
possibility that parallel make with a different output directory can
fail.

Also changed the deprecated EXTRA_CFLAGS construct to ccflags-y syntax.
