package/acpica: remove HARDWARE_NAME make variable override

The HARDWARE_NAME Makefile variable was removed few years ago in
upstream (by Thomas). See [1].

This commit was first included in tag R01_19_17 (version 20170119).
See the change log [2].

This patch removes occurences of this HARDWARE_NAME, since it's now
unneeded. There is no change in the behavior of this build recipe.
