This patch updates architecture specific environment settings for compiling
ACPICA as such enhancement already has been done in ACPICA.

Note that the appended compiler default settings in the
<acpi/platform/acenv.h> will deprecate some of the macros defined in the
architecture specific <asm/acpi.h>. Thus two of the <asm/acpi.h> headers
have been cleaned up in this patch accordingly.
